Design Essentials For Small Gardens

Posted on by Scott Vogt

One of the takeaways from last Saturday’s Native Plant Symposium was that every garden is different. Each landscape takes on the unique vision of the owner. It is cared for with love or neglect and shaped into an oasis that reflects the passions of each gardener. Through plants, art, paths, benches and even ponds, they were, with a bit of effort, able to create their own little bit of heaven.

Some of the gardens were large, but many of them were smaller with challenges all their own. The tiniest landscapes tend to give gardeners the biggest headaches, but they can also give the most satisfaction if designed properly.  These small gardens provide opportunities to treasure and notice the beauty and details of the garden daily. Here are some design essentials for smaller spaces:

Know your space

How much area needs to be landscaped? Is it sunny or shady? What soil do you have and is it wet or dry? What are the boundaries made of (fence, trees, a house, a deck, or a stone wall)? What type of views do you have and do you like what you see?

What type of a garden are you trying to create?

Is it a wildlife sanctuary? Do you want a secluded place to sit and read a book? Is it a space to grow herbs and vegetables along with some beautiful plants? Will you be looking at your garden from within or outside the garden?

Soften the surroundings with plants

The borders of the garden are prominent features that can be enhanced with plants that grow vertically. Whether you have a fence or railing along the edge, plants help define the boundaries. These taller vertical layers will give your garden depth. They develop the illusion that your garden is larger. They also provide privacy and screen out bad views.

Create garden rooms

Not every yard is large enough to create multiple outdoor rooms. If you have the space, however, paths leading to another more intimate area can really be fun. Vary your path, landscaping material and plants in each room so each garden area is unique. Only show a portion of the room to generate intrigue. Interesting lines of plants or edging leading you through the garden can direct you to that hidden sanctuary.

Landscape Layering

I think layering is the most important part of a landscape design. Layers of plants blend the garden together.  This will make the landscape feel cohesive and lush. Mix and match sizes and shapes of plants to create a tiered effect. Hopscotching down from largest in the back to shortest along the path edges with different textures, shapes, and repetition of forms that are in scale with your area will make the garden look full and larger than it really is. If you can pull this effect off, your small garden will be one of life’s simple pleasures.

I know this is not in Kansas but the principle is the same. Layering plants make an impact.

Choosing the right plant

Evergreen trees and shrubs provide structure and interest all year round. Perennials, shrubs and trees add seasonal interest from flowers, foliage, bark and berries. By varying plant types with different foliage such as grasses you add texture and movement in the garden. Scented plants near benches or close to the house waft fragrance through the garden with the gentlest breeze. Flowers that attract butterflies, bees and other pollinators can make a big difference. Trees and large shrubs such as Viburnums add height, privacy, interest from bark, foliage, fruit or flowers, as well as habitat for birds and insects.

Have a place where you can enjoy your creation.

What good is a garden that cannot be enjoyed? Include a bench, comfy chair, fire pit, stone wall or hammock to relax in your garden. Consider whether to build some seating into the plan using seat-height walls to contain flower beds with scented plants.

There is something special about a small garden done right. Landscapes take on the personality of the gardener, through special touches that make your garden special to you. Many people consider these small spaces difficult because they don’t have much to work with, but the key to success with intimate spaces is defining its purpose. That is the starting point. Inspiration is as wild and crazy as you want to be. Have fun with it and embrace the space.

Inspiring Landscapers

Posted on by Brad Guhr

This Saturday, February 24 at our Native Plant Landscaping Symposium, 10 inspiring landscapers will share their native plant gardening stories.

 

A common thread of these landscapers/gardeners (I use these words interchangeably) is that they have each uniquely contributed to my approach and style of landscaping over the years. I have been drawn to their passion for gardening and landscaping. They are botanists, ecologists, master gardeners, landscape artists, and inquisitive students of gardening. Most of them have had successful careers in areas other than landscaping. Yet each considers landscaping a labor of love and finds great joy in working with plants that shape the landscapes around them. Their enthusiasm is infectious. I look forward to hearing their brief prepared stories with photos all being told in a one day symposium format where they can also answer questions. While it is difficult to fit these individuals into specific landscaping categories, I have generally ordered them in speaking sequence from wild and ecological to horticultural and manicured.

I won’t have time to give them each the full and flowery introduction that they deserve. But I will say a bit about their styles and approaches that have influenced me over the last 25+ years.

The Speakers

 

Dwight Platt was my major professor at Bethel College where I studied biology and environmental studies in the early 90s. He introduced me to Lorna Harder, then curator for natural history at the Kauffman Museum. The two of them were responsible for developing the oldest prairie reconstruction in Kansas on the museum grounds, and I was able to serve as a prairie intern with them before graduating. My appreciation for the diverse ecology of the prairie and how prairie plants can be incorporated into landscaping started with them. They inspired me to pursue further education in ecological restoration and landscape architecture.

Dwight and Lorna’s home landscapes utilize many native plants with a focus on attracting biological diversity to those landscapes. Bob Simmons carries a similar approach. His intimate knowledge of host plants and what butterflies they attract guides his approach to landscaping as well. All three of these folks are passionate knowledge seekers of the birds and butterflies around them. They are regular attendees of annual bird and butterfly counts in Harvey County that contribute to citizen science.

My work at Dyck Arboretum with the Earth Partnership for School (EPS) Program has opened my eyes to the power that native landscaping can have inspiring children. Developing prairie gardens on school grounds offers fun learning opportunities through hands-on, project-based learning. High school science teachers Jay Super (Maize) and Denise Scribner (Goddard) are award-winning educators that have displayed how prairie gardening offers a useful learning tool for their students.

Locally grown food is important to our health and well-being and I have long been intrigued by the mixing of vegetables and native plant gardens in our landscapes. The Sand Creek Community Garden in N. Newton has been an example for me in recent years of how growing vegetables and tending native prairie gardens are mutually beneficial. Attracting pollinators and insect predators can only help food plots and they certainly add interest to gardening experience as well. Duane Friesen was the main organizer of this community garden seen as one of the best in Kansas. And as my father-in-law, Duane has also taught me much of what I know about growing vegetables. Joanna Fenton Friesen has a real eye for designing beautiful gardens with native plants and has been an organizer for the perennial flower beds at the community garden. They each have inspiring home landscapes with vegetables and native plants as well.

Pam Paulsen, Reno County Horticulture Extension Agent, is one of the top education resources in Kansas and she has immense knowledge about vegetable gardening, pollinators, and natural pest management. She is also an avid student of the prairie and a great photographer.

Aesthetically arranging native plants in organized assemblages adds enjoyment to landscaping. It also makes native plant gardening, often seen as unkept and weedy, more palatable to the general public. My colleague, Scott Vogt, has a horticulture degree and has helped influence me in this regard by encouraging plantings in groupings. Duane and Joanna with their eyes for aesthetics and surrounding native gardens with edging and mulched trails have also been influential.

Two gardens that I have enjoyed visiting in recent years have been the home landscapes designed and tended by Laura Knight (Wichita) and Lenora Larson (Paola). Their displays of not only native plants, but adaptable perennials and annuals too have expanded my understanding and appreciation for sustainable landscaping. They also have an appreciation for art in the garden, beautiful walking paths, water features, and weeding – all elements that enhance the garden aesthetic experience. Lenora also pays close attention to choosing plants that offer either nectar or food for insects.

I hope you will join us Saturday and experience even a fraction of the inspiration that I have received from these gardeners and landscapers.

Imposter Plants: What it Means to Be Native, Part II

Posted on by Katie Schmidt

This post is the second installment of the Imposter Plants series. In the first post I discussed the differences between native and adaptable, while also trying to clear up the confusing descriptor ‘naturalized’. Here I will dig into the details on what it means to be invasive, noxious, weedy, alien or exotic.

Garden Bullies

On February 3rd 1999, President Bill Clinton signed an executive order that was meant to protect the US from imminent invasion – plant invasion! Non-native plants that become out of control can affect agriculture, ecology, endangered species and human health, and the President was right to be concerned.

There are many definitions for what an invasive plant is, and some are contradictory. Here is my simplified aggregation of the most prevalent ones on the web: a plant is invasive if it is non-native to the region and spreads aggressively enough to displace native plant populations. These plants are not only bullies in the home landscape, they can easily escape into the wild and begin reproducing. Harkening back to the previous post, non-native plants that reproduce on their own in the wild are ‘naturalized’, but the important distinction is that naturalized plants do not degrade habitat and cannot outcompete natives for nutrients, water or sunlight. Invasive plants certainly do, often causing damage to the local flora and fauna.

 

Field bindweed (Convolvulus arvensis) is an invasive plant as well as a noxious weed. Brought here from Eurasia, it quickly adapted to the North American climate and is pervasive enough to choke out native plants and hinder agriculture.

 

Prairie Dock (Silphium terebinthinaceum) is a beautiful native species, but spreads aggressively and can take over your garden. Even so, this is not technically an invasive plant.

Weedy and Noxious

I truly despise the term ‘weedy’. Not only is it vague, it is completely subjective. One person’s weedy plant is another’s favorite flower! The true definition of a weed is merely ‘a plant out of place’; a weed can be any plant, native or non-native, that does not belong in its current place. We use this word to describe the behavior of the plant more than the plant itself. Does it pop up everywhere? Does it come back even after you pull it? Well, a gardener might call this plant a weed, even if they once planted it there themselves. But since it only describes the action of the plant and not the legal status or origins, this word doesn’t hold much weight with me.

Brad Guhr captured this delaware skipper (Anatrytone logan) enjoying the bloom of a native thistle, Cirsium altissimum. People often confuse these with non-native thistles classified as noxious weeds. Our native tall thistle is important to pollinators.

A noxious weed is a different story. Noxious is a legal term and its definition is closely tied to agriculture. Per the 1974 Federal Noxious Weed Act, “a plant that directly or indirectly injures crops, other useful plants, livestock, poultry or other interests of agriculture, or the fish or wildlife resources of the United States” is considered noxious. Confusingly, native plants can be noxious weeds. A noxious weed grows aggressively, multiplies quickly without natural controls (such as herbivory) and threatens agriculture. The USDA regulates these plants and monitors their populations.

Extraterrestrial and Just Plain Weird

Lastly, let’s tackle a few terms that arise occasionally to confuse and befuddle. Though we call some plants ‘alien’, this doesn’t mean they have invaded from Mars. We can use this term interchangeably with ‘non-native’; both mean that a given plant is not naturally found in the area. You may also hear a plant called ‘exotic’. What comes to mind might be tropical, rare, or expensive specimens, but in fact this is just another name for a non-native plant. An exotic plant has origins in another place, perhaps on another continent. Exotic and alien are often bundled together with other terminology – exotic introduced (a non-native plant brought to a new place), an alien invasive (a non-native plant that harms local ecosystems), an exotic naturalizer (a non-native that reproduces in the wild but doesn’t cause major problems) … and so on!

Tamarix is an exotic species native to Eurasia and Africa, but is now spreading aggressively over many parts of the US. So prevalent in some areas, it can lower the water table and deposit large amounts of salt in the soil.

Whether a plant is invasive or naturalizing, native or weedy, can often change based on who you are talking to. Some of these terms overlap in definition, leaving much to argue about. There is even scientific interest in finding a new way to classify these plants to help dispel the confusion. By educating yourself on correct classifications, you can help friends and neighbors understand why they shouldn’t plant invasives that ruin our wilderness. You can also help at our FloraKansas Plant Festival, teaching others that native plants are not just pretty ‘weeds’.

Imposter Plants: What it Means to Be Native, Part I

Posted on by Katie Schmidt

At every plant sale, the same questions come up year after year…

“Which of these are native plants?”
“What is native to Kansas?”
“Why are the same types of plants in the Native and non-Native section?”
“This is a weed, why would you sell this?”
…. and many more!

Our plant sale features many midwest natives as well as ‘adaptable’ plants that are not native but make nice additions to the garden.

The average gardener may feel bamboozled by the idea that there are ‘natives’ and ‘non-natives’, ‘naturalizers’ and ‘introduced exotics’. The public is not well informed of these terms, and many plants have become imposters – invasives masquerading as innocuous beauties and beneficial natives demoted to noxious weeds. Clear classifications reveal the history and behavior of a given plant, but only if we understand the terminology! I have compiled definitions of these terms to help everyday gardeners decode the complex plant lingo. Since there are so many terms to cover, I will split this topic into two posts! This post will cover natives, adaptables, nativars and naturalizers. Stay tuned for the next installment, which will define invasive, weedy, noxious, and exotic.

What is Native?

We must use the word ‘native’ in reference to a specific place or geographical region – Native to the Mediterranean, Native to Peru, or Native to the Great Plains. Otherwise, we could label all plants native to planet earth! In general, scientists consider a plant native to North America if it existed here before European settlement and occurred naturally here during its evolution. In other words, if it required human help to get here, it is not a native species.

At our plant sale, we stock plants that are native to the Great Plains and Ozark region. We sell plants native to Kansas and surrounding states, in order to 1) provide customers with plants that survive and thrive because they are well suited to this climate and 2) get as many plants as possible into home landscapes to support the pollinators and wildlife specific to our area.

Columbus may have thought he was ‘taking possession’ of a new land, but he was also devastating native plants and peoples. Secret stowaways are hiding in the folds of those funny outfits – non-native seeds stuck on clothes and shoes from back home. Europeans brought more and more foreign plant material to the continent with every new ship that arrived. By L. Prang & Co., Boston [Public domain], via Wikimedia Commons

Adaptables and Nativars

At our plant sale, we also offer non-native plants that still perform well in our climate. We call them ‘adaptables’. Albeit a little vague, this means the non-native plant can survive in our climate and is an asset to the garden. Adaptables are often hybrid varieties of native plants. For example, Monarda fistulosa (bee balm) is a Kansas native, but Monarda ‘Cherry Pops’ is a hybrid of the New England species M. didyma. At the sale, we label such hybrids ‘adaptable’. They are relatives of our native species and perform well in the garden, but are not naturally found in Kansas.

Monarda ‘Cherry Pops’ is a showstopper, but this hybrid’s parents are native to New England. In Kansas it does well in part shade conditions that get average moisture. https://www.waltersgardens.com/variety.php?ID=MONCP

This particular adaptable can also be deemed a ‘nativar’ – a fancy term for a native plant that has been specially bred for certain traits. Monarda didyma is a New England native, but the variety ‘Cherry Pops’ is man-made from native parentage. Though not naturally occurring, botanists started with the native variety and selectively bred for vibrant color and prolific blooms. Nativars are beautiful additions to the garden and add exciting colors, but their lack of natural genetic diversity and sterility call into question their usefulness as habitat for wildlife.

The USDA Plants database is an excellent resource – search with botanical or common names to find out their native range and legal status.

Naturalized, But Still Not Native

If a plant falls under the classification ‘naturalized’, it is not and never was a native to the given area. You can identify a naturalized plant by three traits:

  1. It was introduced – brought here by humans, intentionally or unintentionally.
  2. It is well suited to the environment and can successfully reproduce on its own in the wild.
  3. Though it can escape into the wild, it does not upset natural populations.

A good example of this is the common dandelion. Though we think of this as a weed, (more about this tricky word in the next post!) it was intentionally brought over by Europeans as a medicinal plant. It did not require cultivation – reproducing quite successfully in the new world, dandelions are now just part of the landscape. Though it may be invading your lawn, it isn’t truly invasive because it’s not upsetting established populations of native plants. Though not native, it can still be useful! Dandelions are a food source for bees when other flowers are scarce and the leaves are relished by rabbits.

Rabbits love to forage on dandelions. Both of these species, rabbit (Oryctolagus cuniculus) and dandelion (Taraxacum) have been spread around the world by human error.
