Plant of the Month: Lonicera korolkowii ‘Floribunda’

Lonicera korolkowii ‘Floribunda’

BLUE VELVET honeysuckle

When you can combine pollinator attraction and ungulate resistance, this Plant Select® shrub is always a winner. The Blue Velvet honeysuckle gets even better than that, though!

It’s umbrella arching form spreads beautifully in the garden and creates a lovely background filler and focal point that engages throughout the season. In early spring the pinkish, purplish flowers are plentiful and very fragrant. These give way to blue-green foliage in summer and starting in late summer the red berries develop and can become quite plentiful. Bees, butterflies and birds are all attracted to this gem in the garden. There is no fall color to speak of, but the lovely form of the shrub itself makes up for that.

The original blue leaf honeysuckle is native to the central Asia, Pakistan and Afghanistan mountains which means it adapts well to high arid conditions in the western US. It is very pest resistant and extremely drought tolerant once established making it one of just a handful of mid-sized trees that stand out so buoyantly in the xeric garden.

Blue Velvet prefers full sun to part shade, with a wide range of pH soil, and a wide USDA zone (3-8). It mature height is 12’ and is a moderate grower so you’ll see it fill out in the garden in fairly short order. It’s going to get at least as wide as it is tall and has an irregular, arching form to its branching.

While not listed as noxious in any states, it is important to note that this honeysuckle can escape the garden readily after birds eat and drop the seeds. It should be used with caution, especially in the Northeastern US.

Exposing Myself and Other New Year Resolutions

I had a professor once tell me that 90% of inspiration is preparation.

You can find quotes all over the web to a similar effect. There was even a study done recently which indicates that many of one’s creative solutions can be directly correlated to the information one consumes.

And that is why, this year, I resolve to look at more porn.

Plant porn, that is. With some design porn thrown in for good measure. As creators of built works, we must first visualize the outcome we want: What will the finished project look like at every level of detail? What new combinations of plants or materials can we create to engage the people who will inhabit the space? But the longer you are in the profession, the greater your risk of constantly retreading the same path. Utilizing the same design solutions, going with the same plant combinations.

More politely referred to as “visual inspiration,” sexy imagery of other people’s work is a fantastic way to ensure you keep your own work and your enthusiasm fresh. Flicking through other’s design solutions creates an arsenal of ideas at our disposal that you can then piece together in new ways to solve your own design challenges.

And fortunately in this digital age there is no lack of resources! Pinterest is probably the best known imagery resource. (Check out The Plantium’s Beautiful Landscape Ideas board!) Houzz is another great source of design imagery. But perhaps my new favorite imagery resources are the web pages of fellow landscape professionals, especially those practicing in my area. Check out the gallery on the websites of your competitors! You will see different solutions to design and planting challenges you yourself have likely encountered.

But looking at imagery related specifically to the field of ornamental landscaping is only one step in really good preparation for inspired creative brainwaves.

So this year I also resolve to expose myself.

Exposure to many types of thought processes, creative thinking, and problem solving gives you an even broader well to draw from when working on your projects. Maybe you will find inspiration from a painting you encountered, a material you saw while hiking, or even a book you read.

So get out there, surf some plant porn, and expose yourself. The next time you face a design challenge your colleagues might comment on your inspired solutions, but you will know the secret.

CASE STUDY: COLORADO RESIDENCE

CASE STUDY: COLORADO RESIDENCE

FIRM: Connect One Design

WEBSITE: www.connectonedesign.com

Email us at sales@theplantium to submit your Plantium case study.

This Colorado residence used The Plantium’s tools to organize a large number of plants that needed to perform a variety of complex tasks including four season interest and thriving with a pre-determined low water use water budget.

What value did The Plantium bring to this project?

“With over 2,500 shrubs and perennials on the project, the plant list tool in The Plantium helped organize and track 8 different conceptualized planting bed designs among 28 total beds. It was also a lifesaver when it came time to procure material and substitutions were being made left and right. I could search for suitable substitutions, verify contractor-suggested substitutions, and make notes on everything that was accepted. Between building the list and working through the contractor substitutions, The Plantium saved us at least 16 hours on the planting design and installation process.” Elise F.

Where is the site located?

Located at 8,100’ in elevation just outside Aspen, Colorado the home is nestled into a gentle hillside. The aspect varies throughout the site and the soils are rocky, sandy clay. The pH is generally average to slightly acidic. It is USDA zone 4 so most of the environmental challenges are related to cold winter temperatures and a low water use water budget. The dry shade bed designs were by far the most challenging.

What were some of the planting design constraints?

The front of the property is sheltered, while the rear of the property is on an exposed, west-facing slope, so we could not continue the same palette of plants from the front to the back. In the rear of the house the planting also had to transition in a purposeful way to a revegetated native grass and wildflower meadow bounded by blue spruce and quaking aspen. To ease the abruptness of the transition, the planting design intersperses cultivars of the wildflowers appearing the meadow. Overall, the project had to meet a water budget goal as well. We could only use limited to no high water plants and had to limit medium water use plants to shadier areas. The remainder of the beds had to accomplish the following goals using low or low-medium water use plants.

What were the planting design goals?

The front of the house is intended to blend with the adjacent mature aspen groves, while providing the client with significant textural and color interest throughout the growing season. A varied palette of plants, all under 4 ft. tall, provides foliar and flower interest to the front entry while allowing the stately white trunks of existing and newly planted quaking aspens to make their own statement against the architecture.

The landscape transitions to a more modern approach in the rear of the house. The planting design is intended to bolster the sweeping forms and modern aesthetic of the hardscape design with bold, curvilinear planting blocks. We wished to avoid the monotony of large, monoculture plantings. Instead, we opted for groupings of a handful of plant types carefully chosen conveyed a strong sense of color or texture throughout the year. Each large grouping is placed to contrast with adjacent plant blocks. In this way we achieved a modern design with a more gardenesque level of interest and diversity.

What were the overall design outcomes?

While deceiving in the installation photos because everything is blooming at once, we are excited to see the progression of color throughout the planted garden beds in the next growing season. The larger mass plantings will have great textural qualities while also blending back into the native revegetation areas, creating a seamless look from afar but a more intricate feel up close. Stay tuned for pictures and lessons learned after year one and year three growing seasons!


 

 

 

 

 

 

 

 

 

Designing with Winter Interest Plants

In many areas of the country winter captures nearly four to six months of the year so designing with winter interest plants is a hugely important aspect of our designs. While the summer garden can be intricate and detailed, the winter landscape tends to need a bolder and more gestural consideration. We always ask the question….. will this garden also be compelling even in the winter months? We strive to consider all the aspects of garden design (form, flow, accent, figure/ ground, etc.) from a seasonal interest perspective. We look to accomplish four important goals in our winter landscapes.

DESIGN GOALS

  • Four-season interest in our plant selection. Structures and physical elements consider snowpack conditions and subtle winter colors. Outdoor spaces still seem warm and inviting. Materials can withstand harsh winter environments.
  • The beautiful, subtle and evocative landscapes that exists around us every day inspire our cultivated landscapes. A dark black perennial stream that cuts sharply through the stark white snow, the bright yellow and red of the willows and dogwoods in the spring when the sap flows but the snows still fall, soft rolling landforms covered in smooth buttery snow or the dark and light contrast of an evergreen against a snowy or subdued backdrop…. these are the inspiration behind our gardens.
  • Choosing winter interest plants for the garden is very similar in principle to our summer gardens, for example, uncut native grasses can provide soft texture and great movement even covered in snow. Large swaths of red twig dogwoods and the striking bark of a quaking aspen or birch grove can be a bold statement that is even more dramatic in the winter. Evergreens are easy choices to still have great structure in the garden, creating and maintaining spaces even in winter. Sizing winter interest plants to your average snow conditions so they will still stand out is an important consideration.
  • As winter conditions in many parts of the country vary greatly each year, desgning with winter interest plants can be even trickier. Winter resiliency (72 degrees in NY, NY on Christmas 2015, or 19 degrees in 2013) is important and plants that entertain all sorts of conditions are important.
  • Fire and water features, structures or sculptures often provide a focal point in our gardens because they can function well in both summer and winter. Place these features where the microclimate will be comfortable year-round…. Wind protected and south facing.

GARDENER RECOMMENDATIONS

“Try to resist cutting anything down that doesn’t need it before the Spring. The seedheads of perennials and grasses such as veronicastrum, yarrows, showy stonecrop, prairie dropseed, oat grasses, switchgrasses and feather reed grasses are exceptional sculptural elements in harsh frosts and in early snows before they are completely inundated in deep late winter snow.”

“Winter watering is often forgotten in the dormant garden. Many shrubs and trees are lost to dry soil and drying winter winds than anything else. Consider your plant selections carefully and pay attention to those that still need some winter moisture to emerge healthy and thriving in the spring.”

“Contrast tends to be the most dramatic tool at our disposal in the winter garden. Consider a chartreuse Pfitzer Juniper or the yellow twigs of a Yellow Mountain Willow against a backdrop of deep green pines. These garden components will catch the eye even in the darkest months of winter.”

“Use deciduous trees and tall shrubs to protect south facing outdoor spaces. This will provide shade and cool temperatures in the summer and allow the warming sun in during the winter months.”

 

SOME GREAT WINTER CHOICES

Cornus argenteo marginata – An excellent choice as it is one of the reddest of the red twig dogwoods in winter yet provides outstanding summer interest with attractive variegated foliage and the ability to thrive in full sun.

Ilex and other structural evergreens stand up well to heavy snows provide robust structure with or without snowy conditions.

Rosa rugosa – Large red rosehips in the winter provide great interest in natural gardens.

Japanese Maples –The twisted and contorted branches of Japanese maples provided an unprecedented living sculpture to gardens. Best placed on the north side of buildings where protected from winter sun and wind. There are many cultivars being grown by nurseries that combine Korean and Japanese Maples for a combination of hardiness and aesthetics.

Tsuga canadensis spp. – Canadian hemlock come in many shapes and forms and provide an excellent alternative to junipers.

Acer griseum – Paperbark maple. When grown in and amongst the white bark of aspen trees, this ornamental tree with a cinnamon colored peeling bark adds another dimension to a garden in the winter.

Polystichum and Polypodium –  (it’s called a Christmas fern, after all!) In broad swaths ferns can add tremendous texture and pair well when punctuated by the broad seed heads of a yarrow or a tall stonecrop.

Drumond, Coyote or Yellow Mountain Willow are good choices for nice yellow coloring on their new growth and early spring catkins. The Dwarf Arctic Willow with purplish branches and early spring catkins doesn’t have its counterparts yellow coloring but makes up for with it a very graceful arching habit.

Fruiting shrubs and trees have no rival to the color they bring in the winter garden as well as the year-round food for birds that are brave enough to stick out the winters (yew, crabapples, snowberry, etc.).

Hedra helix – English Ivy and other ivy while having been used for years for winter garden interest, we caution you to use tools such as The Plantium to verify noxious status in your area! These plants are often still commercially available even while state’s work to list them as noxious and invasive!

With nearly 2,000 plants showing with the ‘winter interest’ filter, The Plantium can help you with designing with winter interest plants in your garden!

Soil Depth and Plant Selection

Minimum soil depth for plant growth is a frequent subject of discussion of late and while you cannot search The Plantium based upon soil depth, we thought we’d gather some information to assist in your criteria based plant designs!

Let’s first look at the question at hand. As designers and installers we are asked to create landscapes in all sorts of conditions. Often these conditions are challenging and not necessarily conditions that plants might face in their natural environments. That said, we have all seen these images at some point in our lives…. the beautiful and resilient plant that appears to be growing happily, in what appears to be NO soil depth AT ALL!

 

 

 

 

 

 

 

 

 

For those looking for answers regarding bed construction and just soil depth in general, let’s send you to one of our Plantium brands for some fantastic basic information regarding bed construction in the field.

https://www.provenwinners.com/learn/make-your-bed

Soil depth for OPTIMAL plant growth in more challenging situations such as green roof conditions, large planters, tree wells, etc. is dependent on four main factors. These factors are proper drainage, proper plant selection, plant longevity, and soil depth to plant height ratio. We’ll discuss these factors in this order because the very last issue you should be considering in your plant design is soil depth. If you have not addressed the first three issues in your bed design then regardless of soil depth, plants will not thrive.

Proper Drainage

Whether your planting bed is in the lawn, green roof or contained planters, proper drainage is crucial. While certain plants can survive inundation in a natural setting, standing water or improper drainage will QUICKLY de-oxygenate and compact the soil in contained situations and kill the plants. There are many ways to tackle drainage and all are dependent on the design situation. Working closely with the horticulture team is the best way to find an effective drainage solution.

Proper Plant Selection

Let’s look at those tough little plants growing in the cracks and crevasses! You need to keep in mind the type of plant you are specifying when dealing with challenging planting situations. Plants that grow in these conditions in the natural world tend to be tough, resilient, vigorous, and drought tolerant plants. If you have all the right soil and bed conditions but choose more sensitive plants, it is likely that those plants will struggle. Also, remember that as the soil profile for any plant is constrained so will the plant’s natural habit be constrained. Street trees planted in minimum soil volumes will never reach the full mature height or width that they would under optimal growing conditions.

 

 

Plant Longevity

Planting designs are being designed and installed with a maximum 20 year life span. A controversial statement, perhaps, so feel free to challenge it! It appears long gone are the days of an Olmsteadian landscape that appreciates with time and just barely reaches its full glory at 20 years. Here at The Plantium we vehemently disagree with this trend and firmly believe that criteria based plant selection can reverse this trend. Better plant choices! We’d love to hear your comments on this issue!

All that said, green roof and enclosed planter situations pose different challenges. Small planters and shallow green roof systems need very carefully management to maintain soil health and ultimately plant health. The shallower the soil profile the more quickly that soil will be depleted of nutrients and micro-organisms crucial to the plant’s health. If a refresh of the plant material (and soil) is planned over time, then shallower soil profiles can be a great fit. If the design contemplates trees and shrubs that are intended to grow to maturity over time, then a more significant soil depth should be considered.

Soil Depth

On to the question at hand. Let’s simplify the soil depth for optimal plant growth under container type situations into the following categories. Again, exact soil depth is probably debatable by many so we welcome other thoughts from our expert crowd!

Plant Type Plant Height Minimum Soil Depth
Annuals Any 3”
Turf Grass NA 4” (3” in warm climates)
Perennials <8” 4” (3” in warm climates)
Perennials 8”-16” 6”-8”
Perennials/ Ornamental Grasses/ Shrubs 16”-24” 12”-18”
Perennials/ Ornamental Grasses/ Shrubs 2’-6’ 24”
Shrubs/ Small Trees >6’ 3’ Minimum (should consider overall volume as well)
Trees All Should be calculated on overall volume for each tree and not just soil depth

 

Maintenance

Lastly, on-going maintenance is the greatest issue facing these planting designs. Over-watering is perhaps the most frequent maintenance faux pas committed against our container plants. Carefully working with the maintenance team is critical to head off this issue early on.

Happy Planting Y’all!

Importance of the Allergy Friendly Landscape

Most of us think summer sneezing just ‘comes with the territory’ but did you know that you can alleviate some of it with an allergy friendly landscape!  As landscape professionals, the concept of an allergy friendly landscape is a crucial one. Regardless of the scale of a project our understanding of high pollen generating plants is critical to making some changes for the better in our cultivated landscapes.

Wind blown pollen

Wind blown pine tree pollen. Makes me sneeze just looking at it!

Background

Most of us suffer from just a little sneezing and sniffling from seasonal allergies but the implications of high pollen rates can be far more serious. “Deaths from asthma continue to climb each year at alarming epidemic rates”.1 While the causes of these increases can be debated it is clear that high pollen rates play a role in many health related issues, especially in the young, old and those with compromised respiratory and circulatory systems.

Studies have shown death rates among high-risk populations increase on days with high pollen and high pollution. Similar to the association of very hot or very cold weather to higher death rates, one cannot attribute it directly to the weather condition but rather see a correlation in high-risk populations.2 Impacts like thunder death outbreaks also bring home shocking impacts of high pollen in urban settings.3

So, how did we arrive at the increases in allergies and asthma? We all know the issue relates to high pollen counts, but what is pollen and has atmospheric pollen been on the rise in recent years? Pollen is the microscopic grain carrying the male gamete of a plant that will pollinate (via transport by insects, birds, wind, etc.) the female ovule of a plant. This microscopic grain is both an irritant and a nasal allergen in humans (and other animals; yup, dogs get allergies). Anemophilous plants generally cause the most allergies because they pollinate primarily by wind. The pollen grains of those plants are light and small, in order to be easily dispersed by the wind (and therefore tend to stay airborne and easily breathed in by humans). The role of female plants in an allergy friendly landscape is critical because they are attractive (for sure 🙂 )! The pistil of female plants is STICKY in order to capture the pollen grain. In an allergy friendly landscape female plants (and flowers) are important because they both do NOT produce pollen, AND they pull pollen out of the air with sticky attractiveness! Two other important aspects of pollen creation are important to understand as well – pollen production is increased dramatically with additional CO2 in the atmosphere (urban settings) and changes to the timing of pollen generation is being sparked by increased climatic temperatures.

Microscopic Helianthus Pollen

Microscopic Helianthus Pollen – it sure looks like it would irritate anybody’s nose!

So what does this have to do with the cultivated landscape and an allergy friendly landscape? This is where the concept of botanical sexism comes into our vocabulary. “Arborists often claim that all-male plants are ‘litter-free’ because they shed no messy seeds, fruits or pods. In the 1949 USDA Yearbook of Agriculture, which focused on trees and forests, this advice was given to readers: ‘When used for street plantings, only male trees should be selected, to avoid the nuisance from the seed.’ In the years following, the USDA produced and released into the market almost 100 new red maple and hybrid-maple-named clones (cultivars), and every single one of them was male.”4 At The Plantium, we believe male cultivars have an important place in the landscape, but it is important to understand that the use of male (and only male) cultivars and overall plant selection play the most important role in developing an allergy friendly landscape.

Scope and Scale

When and where it is important to think about an allergy friendly landscape? There are many projects where understanding the right plants for a low allergy and allergy friendly landscape are important. Being conscious of pollen generation on all your projects can help address the growing issue of high pollen in the cultivated landscape. Our responsibility as landscape professionals should be taken seriously! Consider your client when embarking on a residential design. Just asking the question about any allergy or asthma sufferers in the household (and then designing an allergy friendly landscape) can help make a successful landscape and a happy client. Allergy friendly landscape plant selection is most important around high risk populations, including playgrounds and senior living projects. Finally, projects in urban centers should be addressed carefully as the greatest population of allergy and asthma sufferers per capita reside in cities.

Amaryllis Stamen

Up close and personal on the Amaryllis stamen. The sticky pistil of an amaryllis flower gathers up all this pollen for fertilization!

Making Great Plant Choices

All of this background begs the question… what do we do now? Here are a few thoughts.

  1. Understand and educate yourself on the benefits of the allergy friendly landscape.
  2. Familiarize yourself with the OPALS rating system. Thomas Ogren created the first and only known rating system that ranks the allergy potential of plants.
  3. Discuss the need for an allergy friendly landscape with your client.
  4. Educate yourself on types of plants that might fit in an allergy friendly landscape and follow a few best practices such as:
  • Gender balance the landscape.
  • Use fewer wind pollinated species.
  • Encourage sterile cultivars and showy flowers (most plants with big colorful flowers are insect pollinated! Bees welcome?!).
  • Avoid high pollinators: male only willows, poplars, aspens, ash, (fruitless) mulberry, cypress, junipers, yews, myrtles, currants, etc., olive trees, Bermuda grass. Fruit trees are good but nut trees tend to be allergenic.
  • Develop maintenance manuals for your clients that encourages trimming of existing high pollinators and good maintenance of installed plants (e.g. trimming privet before it flowers). The Healthy Schoolyards Initiative5 has a great start at a list of maintenance measures that can be undertaken on existing landscapes.

The Politics of Allergy Friendly Landscapes

While it appears uncertain that low pollen ordinances are having an impact, landscape professionals should be aware that there are a growing number of urban centers enacting pollen control ordinances, including Pima County, AZ, Clark County, NV, Albuquerque, NM, Phoenix and Tucson, AZ, and El Paso, TX, among others. Other cities such as Louisville are embarking on some truly innovative approaches to understanding and addressing the epidemic.

Conclusion

While we can thank pollen for so many wonderful things like solving murders (it’s a plant’s fingerprint!), determining the age and quality of coal seams, and our delicious fruits and vegetables we now need to be stewards of our own air and address the issue of excessive pollen in our cultivated landscapes!

Designing with Dog Friendly Plants

Ever wonder how we get our yards, parks, and streetscapes to be ‘dog friendly’? As in, how do we design a urine and trample resistance landscape filled with dog friendly plants? Well, let’s start with thinking about some alternative groundcovers that can take a little beating. These are plants that can be used as an alternative to turf. Turf alternatives can save water AND help fight off the brown patches that come with a ‘dog heavy’ landscape. A couple good examples in the attached pdf include Elfin Thyme and Ajuga. These are just two great choices, but you can always use your filter criteria and select low growing plants that can withstand foot traffic. In The Plantium’s filter criteria you’ll find the foot traffic filter under ENVIRONMENT.

The second issue is urine resistance. While this is NOT a filter in The Plantium, the attached pdf has some tried and true choices that can withstand the excessive nitrogen content in dog urine. Again, not an exhaustive list but a good start. Remember to also consider any plants that are TOXIC to pets and avoid those. Sending your little furry friend to the vet would definitely NOT be considered dog friendly plants! For those Plantium users, this is a filter criteria under WILDLIFE. For those of you not yet in The Plantium you can visit the ASPCA site (Plantium’s filter criteria is WAY easier, though!) 🙂

Lastly, and perhaps most obvious would be water. The faster you can wash away any leave behinds from the doggie visitors, the better chance of avoiding the burn spots, so let’s take back those brown patches and get into our dog friendly plants!

Designing with Bulbs

We’ve all read some great articles about designing with bulbs (and corms) so why not keep the discussion going? Designing with bulbs can be daunting. Visiting the botanic gardens in spring nearly blinds us with the glory of huge swaths of spring bulbs. Vast beds of daffodils, crocus and tulips are the sure sign that spring has sprung. A bed of crocus dusted with snow is an iconic image of early spring. Now let’s focus our attention on some other aspects of designing with bulbs, year-round interest and designing to specific bloom heights.

5177_WPFL_Eremurus-himalaicus-WMC_001Dahlia 'XXL Veracruz' AZTEC

The opportunities presented by designing with bulbs can be taken advantage of year-round with a little planning and great execution. Gladiolus and Dahlias can bring in a huge color punch during the mid-summer to late summer in warmer climates and similarly Allium and Autumn Crocus in colder climates. Similarly, lilies can provide a tremendous amount of foliar interest in the early summer months and then finish the season off with splendid color in late summer and even through the fall. The first step is to sort through the vast array of choices in bulbs and corms and remember what you are trying to achieve. Here a sampling of a season-long list for a garden in zone 6a, that’s scented, and attracts bees, hummingbirds, and butterflies. This short list from The Plantium yields plenty of choices to keep you thinking about designing with bulbs all season long! There are so many more to choose from!

Bulb Flowering Season

The next consideration is careful planning around bloom height. This same list now includes plant (foliar) height vs. actual bloom height. Not planning for the bloom height of late blooming bulbs is a common mistake. Some height variations will be minimal but some can be more than a foot or even up to 4’! Check out the Foxtail Lily. Many of these bulbs are not known for lush foliage so you can place them further back in the garden (than you might normally based solely on foliar height) with other perennials or shrubs around them. This leaves their bloom to surprise us when the time is right!
