KNPS Field Trips are BACK!
Ballard Wildlife Management Area

Date of trip: 07/31/2021
Start time: 9:00 am to 12:00 pm Central Time
Location: Ballard County
Difficulty of hike: Easy – We will caravan/car pool on the gravel roads in the wildlife management area, stopping to view a variety of native plants and habitats. At a couple of the stops we will walk distances of under a 1/2 mile.

It’s been well over a year since KNPS has been able to have field trips exploring the diverse botany of Kentucky. We are excited to get back into the field with our first field trip since the start of the pandemic. Join KNPS Board Member, Jeff Nelson, Ballard WMA employee, Gerald Burnett, and KNPS member, Bob Dunlap, as as we explore the native plant ecosystems in the wetlands and river bottoms of the Ballard WMA in Ballard Co.

Ballard Wildlife Management Area is 8,000 acres located in the Ohio River bottomlands ecoregion in far western Kentucky. The WMA is mostly wetland with 39% of the acreage in wetland, 28% forest, 27% open land, and 6% open water. Much of the wetland is comprised of rare, cypress-tupelo swamps and sloughs which many Kentuckians have not had the opportunity to experience. The Office of Kentucky Nature Preserves lists cypress-tupelo swamp as a state endangered ecosystem.

We will caravan (carpooling as much as possible) around the WMA, stopping to examine the botany of Ballard’s diverse ecosystems. We should see several uncommon, wetland plant species, some in flower. Although we will not be hiking any distance, we will be taking walks of less than 1/2 mile at a couple of stops, all on the road or trails. We will walk into areas off the road to get a better view many of the plants. There is likely to be some muddy spots where we will be walking, so be prepared. At the end of July, it will be hot and humid and there will mosquitos and ticks, so bring plenty of water and insect repellent.


Directions: We will meet at the WMA Office at 864 Wildlife Lodge Rd, La Center, KY 42056.

Heavenly bamboo (Nandina domestica)

By Heather Doolin, Office of Kentucky Nature Preserves

Heavenly bamboo (Nandina domestica), also commonly called sacred bamboo, is an evergreen shrub, vaguely resembling bamboo.  Heavenly bamboo began its journey in North America as an ornamental plant, escaping cultivation and invading forests of ten southern states, Kentucky being included in those affected.

From the Lady Slipper Archives: Wild Bergamot – 2001 Wildflower of the Year

The Lady Slipper newsletter of the Kentucky Native Plant Society has been published since the Society’s founding in 1986. We occasionally feature an article from a past issue. This one, about one of Kentucky’s loveliest natives, the Wild Bergamot, first appeared in the summer of 2001, Vol. 16, No. 2. If you would like to see other past issues, visit the Lady Slipper Archives, where all issues from Vol. 1, No. 1, February 1986 to Vol. 34, No. 1, Winter/Spring 2019 (after which we moved to this blog format) can be found.

The author, Mary Carol Cooper, left a huge legacy to the native plant community when she passed in 2016. In almost every native plant gathering, her name is mentioned and a moment is given over to appreciate her knowledge, which she freely shared. Her passion led many of us to our love of natives; she was a mentor and friend to many of us.

Wild Bergamot – 2001 Wildflower of the Year

by Mary Carol Cooper, Native Plant Program Coordinator, Salato Wildlife Education Center

Wild Bergamot (Monarda fistulosa) has been selected as the Salato Wildlife Education Center’s Wildflower of the year 2001 by wildflower enthusiasts from all across the state. The Wildflower of the Year is chosen based on the number of nominations it receives and how well it fits the established criteria (must be native, common and widespread across the state, seeds must be readily available, must be easy to grow, and must have wildlife value).

Wild Bergamot is common in old fields, thickets, prairies, and borders thoughout the state. It is a member of the mint family and has spicy-aromatic leaves that are opposite and ovate-lanceolate on a square stem. It has slender two-lipped corollas about one inch long densely aggregated in terminal clusters subtended by conspicuous bracts. The corolla is a pale lavender. Wild Bergamot ranges in height from three to five feet tall depending on the habitat. It is a short-lived perennial that rapidly forms colonies in both moist and dry soil. It is very versatile, as it will tolerate clay soils and drought and will grow in full or partial sun.

Wild Bergamot is a premiere nectar source for butterflies, moths, and hummingbirds. Indigo buntings are known to build their nests in the stems of this plant. It blooms from June through August, providing food and shelter all summer long.

Historically, physicians used leaf tea to expel worms and gas. The Native Americans used the leaf tea for colic, flatulence, colds, fevers, stomachaches, nosebleeds, insomnia, heart trouble; in measles to induce sweating, and poulticed leaves were used for headaches. The pioneers made a lotion of boiled leaves for treating pimples and skin eruptions. Today, Wild Bergamot is still used for headaches and fever and it makes a great tea. Its flavor is similar to true bergamot, the oil of a Mediterranean citrus fruit that flavors Earl Gray Tea. It is also excellent cut for fresh bouquets.

Wild Bergamot seeds and plants are available from many native plant nurseries and are fairly inexpensive. It is also very easy to propagate either by seeds, cuttings, or division. Seeds sown in January should be kept moist and cold (40° F) for 90 days to cause germination. Since the seedlings are tiny and slow growing, they should remain in the flat for 6–7 weeks after germination before being transplanted. To propagate by cutting, take stem tip cuttings, 3–4 inches long, any time from May to August. Remove the lower leaves and all flower or seed heads, dip cutting in rooting powder and insert at least one node into a sand and perlite rooting medium. Place cuttings in an enclosed chamber and mist them several times a day. In 4–5 weeks, cuttings are well rooted and can be transferred to the garden in the early fall. To propagate by division, divide mature clumps in March before they send up stems. Dig up the plant and using a pair of pruning shears or a sharp shovel, cut the clump into sections. Replant and water the division immediately.

From the editor

Last month, The Lady Slipper introduced a new column, Kentucky Yard Restoration. In that premiere article, Karen Cairns describes her restoration project as a labor of love. I think most of us can identify with that statement.

Years ago, I planted natives for the birds and butterflies, without realizing that I was providing habitat for many other Kentucky creatures. I lived in an ordinary neighborhood with a few old trees, a small back yard, and houses in every direction but up. The birds came. The butterflies came. But so did the frogs, box turtles, rabbits, raccoons, and bees. I still get goosebumps when I remember finding that first bullfrog.

One morning, I found a neighbor in my backyard wandering around looking at it all. He asked how we installed the small pond–and when I say small, I mean it. But it was cozy enough for the green frog who took up residence there.

Each August, the hummingbirds were so numerous and bold, they would fly between our heads while sitting in our bench swing. I once had one check me out by hovering about a foot from my face and squeaking at me for a bit. What she was telling me, I don’t know, but I cried. I just stood there and cried because the interaction was so amazing.

Over the years, I noticed that some species were more abundant than others, and we began referring to things that happened during “titmouse summer,” “red-winged blackbird summer,” and so on. We had a pair of rose-breasted grosbeaks that stopped by Mother’s Day weekend without fail for many years. A red-winged blackbird flew in at the same time every day to chat with our dog. After a hard storm, a pair of bluebirds took refuge until they were strong enough to rebuild. They returned often to feed their offspring.

When we moved, I started over. Our new home had a Bradford pear tree and some holly bushes. If you think I despaired, you are wrong. I was excited, and I started all over again. After ten years, my home is surrounded by trees, shrubs, flowers and grasses–almost all native. The backyard bumps up to a field that connects with a wild and protected area. My backyard blends right into that field. Some might call it ugly; I think it’s beautiful. It is habitat, and now I take stewardship seriously–so seriously, that my mantra has become “Every yard matters.”

This small area is winter habitat and to some people, ugly.
In early spring, it’s mowed. Throughout the spring, summer, and fall, native blooms fill it.

If we can convince a few of our neighbors to return just a small section of their yards to the wild, we can reconnect to the wild in a way most of us think impossible. Imagine the corridors of habitat we could create. Many will be slow to adopt to this idea, but we must try. We have no choice if we are to become the stewards we are meant to be. I want my children, my grandchildren, and my great-grandchildren to know the joy of discovering a frog in their small pond. We don’t all start out with stewardship as our end goal, but that’s where a restoration project takes us.

We want to share your yard reclamation stories. You don’t have to be a great writer–we only need your passion and your story. Please consider sharing your Kentucky Yard Restoration story. You can contact us at LadySlipper@knps.org.

Five reasons not to use landscaping cloth in native beds

By Susan Harkins and Jonathan O.C. Kubesch 

A recommendation to not use landscaping cloth in flower beds, is usually met with a lot of resistance. Laying cloth is standard practice among professional landscapers and home gardeners. However, as we become more aware of the importance of natives in our landscaping, it’s also time to give up the cloth. There’s nothing natural about it, and it works against you in native plantings. Initially, landscaping cloth sounds like a great idea, but in the end, it is usually more trouble than it’s worth and there are a number of reasons why.  

Cloth compacts the soil 

Compacted soil is not a natural growing medium regardless of what you’re planting. You want loose crumbling soil that drains well and has plenty of nutrients. Plants grow better when their roots are allowed to grow easily, and water and nutrient intake is easy. Under landscape cloth, you will find compacted soil—it’s hard to dig and plants are seldom as healthy as they should be.  

After installing landscape fabric, soil quickly begins to lose its crumbly, granular structure. In nature, many natives require that spongy surface in order to grow and establish. A side effect of sealing the soil surface is that it hinders recruitment of many delicate natives from existing plants.  

Now consider that cloth seldom stays where you put it. Usually, it’ll work its way to the surface, where it’s ugly. Sometimes cloth goes deeper into the soil. Eventually, you could plant right over it, never knowing it’s just an inch or so below your new planting and that will definitely affect that plant’s health.  

Weeding is more difficult 

Initially, cloth will deter weeds, but nature is tougher than the cloth. Eventually, the weeds will return and guess what? Pulling those weeds will be a nightmare because that layer of cloth is under the surface acting as an anchor! You’ll have to dig it out most likely and doing so will leave a hole in the fabric, which means more weeds. While you might have fewer weeds, those weeds will be more difficult to remove. Wild violets (Viola spp) are notorious for rooting into imperfections in landscape fabrics.  

If that weren’t enough, consider what these cloths are made of: petroleum and other chemicals, which leach into your soil. As we become more environmentally aware, landscaping cloth is no longer a reasonable choice.  

Long term, landscape fabric doesn’t allow the gardener to shift landscapes in tune with horticultural and environmental trends. It arrests the landscape because it takes a fair deal of work to remove and can be a pain to remove around existing plants.  

Cost 

Landscaping cloth isn’t expensive until you consider how much of it you need to cover all your landscaping and native beds. You’ll also need pins to hold it down. To hide it, you’ll cover it with mulch. It adds up, and it’s totally unnecessary. A more natural alternative is old newspapers covered in wood or straw mulch. While these barriers will eventually break down, they are easier to work with over the years and provide better water flow into the soil.

Reseeding 

Many natives propagate by self-seeding. Landscaping cloth makes that close to impossible because the seeds never make contact with the soil underneath the cloth. What happens when you want to add new plants? You must cut the cloth to add plants, bulbs, and so on. Every hole in the fabric is an opportunity for weed seeds in the underlying soil to germinate and break through.  

While your natives may fail to reseed because of the cloth, weeds are different. Seeds traveling by air or deposited by birds and other small mammals won’t mind the lack of soil a bit. They’ll sprout in the mulch and send their strong roots through the cloth.  

It isn’t natural 

There’s nothing natural—or native—about landscaping fabric. If your motivation is stewardship, I probably don’t need to say anything else. Regardless of whether it’s under mulch, rock, or even soil, a cloth barrier traps creatures below ground. You’re killing creatures that live in the soil and keep it healthy!

When you hike in the woods, you don’t see landscaping cloth. Remember, you’re trying to create, or mimic, a natural environment. In looking to mimic native systems, consider materials that you see in the woods or meadows. Leaves and duff, as well as thatch or straw, are the natural mulches in ecosystems. They provide a level of control on the weedier species, but they also break down over time to support new plants. While we may not mimic that same level of space and time variability in our yards, using natural materials is important! 

What to use instead 

Establishing a new bed takes work with or without putting down landscaping cloth but eliminating that cloth will save you some labor and money. What you use to reduce weeds is up to you and the soil’s health should be a factor. If it’s compacted, amend with organic matter before you do anything else. Rototilling the area isn’t necessary and actually destroys soil composition, so avoid rototilling unless the soil is severely compacted.

Remove turf or cover it with layers of cardboard or newspaper to smoother it. Both will quickly degrade and help amend the soil. Wet the cardboard or paper to keep it in place. The next step is a few inches of good arborist chips. You can buy mulch, but most tree servicing companies will gladly dump a nice mound of chips for free. Chips aren’t consistent in size and color, so they look more natural—more like a forest floor. They degrade quickly though and will need supplementing often if you continue to use chips.  

If you plant immediately, cut through the cardboard and plant in the ground and keep the area well watered until the plants are well established.

You can avoid remulching eventually, by using native groundcovers as green or living mulch. It takes a few seasons, but eventually your plantings will be so full that few weeds can’t set up home. You will still have to weed occasionally but maintaining this spot will be much easier than if you laid cloth underneath.  

Meadowscapes and other areas where a mix of native species provide aesthetic vistas at lower maintenance requirements than traditionally manicured beds. Using grassland species will require occassional mowing or spin-trimming, but these areas are great for self-mulching and weed control. 

We add natives to our yards for several reasons. Mine started with a love of birds, butterflies, frogs, bugs, and so on. At the time I wasn’t thinking about being a good steward of the land, but that is what happened. Regardless of why you plant natives, you will approach the addition as you would any other flower bed by preparing the area, and if that includes landscaping cloth, please stop and reassess your decision. 

The Many Benefits of Groundcovers in a Garden

By Katrina Kelly, owner of EARTHeim

I’ve never met a gardener who doesn’t want to reduce maintenance in their garden. While it can be fruitful to care for a garden, sometimes we just want to sit back and relax while enjoying it! Groundcovers are one solution to reduce garden maintenance. The fewer blank spaces there are, the fewer chances for weeds and the less need for mulch. There are many native groundcover plants that are great choices in garden settings.

Groundcover usually refers to plants that are low-growing and have a spreading or creeping habit. Some perennials that grow taller can be used like a groundcover. There are many groundcover species commonly seen in the landscape, mostly non-native ones like Vinca major, Pachysandra terminalis, or Liriope. Unfortunately, many non-native groundcovers are also considered invasive like wintercreeper (Euonymus fortunei), and English ivy (Hedera helix).

There are many reasons why a groundcover may make a great choice. Groundcovers can help fill large spaces, especially if you’re on a budget. The groundcover will spread over time, so you can buy fewer plants to get started. Many native groundcovers are manageable in the landscape even when left to naturalize.

In a design sense, using large swaths of groundcovers can create a simple, refined garden space. Use them to create a monochromatic palette or greenery for foliage interest. For groundcovers that bloom, large blocks of color create nice views along a roadway or as a backdrop to a garden.

One of my favorite ways to use a groundcover is underneath trees and shrubs. Because it can be difficult to reach underneath a shrub to pull weeds, planting a groundcover helps with this dilemma. I often show up to client’s homes, where I find invasive honeysuckle growing inside another shrub. This situation is often overlooked, so when you plant a shrub, consider planting a companion groundcover underneath.

In an ecological sense, native groundcovers can be used to suppress invasive species in an area. For example, wild ginger has a dense root structure, which prevents anything else from growing in it. Groundcovers will compete with other plants through its root structure, shading the ground, and absorbing moisture from the soil. Use this behavior to prevent weeds.

Some plants can be considered groundcovers even though they are not low growing. Ferns, like ostrich (Matteuccia struthiopteris) and interrupted (Osmunda claytoniana), will spread by underground rhizomes or stolons to form small colonies that are great for filling in sections of a shade garden. River oats is a nice ornamental plant that looks like a grass. It readily seeds, but it is great in areas where you need to keep out invasive plants and to prevent soil erosion.

Like river oats, grasses, and sedges (Carex species) make great groundcovers on sloped areas that are prone to erosion. These plants in a residential setting work well because they mimic a lawn but eliminate mowing along steep slopes which can be dangerous.

Sedges are another low maintenance alternative. They are the only plant I consider no maintenance because many species don’t need cutting down in spring. They are safe choices in an easement garden between the sidewalk and street since they don’t block views. A few can tolerate being stepped on occasionally in these high traffic areas.

A few part shade to shade groundcovers to consider are wild ginger (Asarum canadense), Allegheny spurge (Pachysandra procumbens), stonecrop (Sedum ternatum), woodland phlox (Phlox divaricata), creeping phlox (Phlox stolonifera), golden groundsel (Packera aurea), green and gold (Chrysogonum virginianum), and dwarf crested iris (Iris cristata). Some of these can tolerate nearly full sun conditions. For full sun conditions try moss phlox (Phlox subulata), pussytoes (Antennaria virginica), and prairie smoke (Geum triflorum).

Success with groundcovers starts with the right plant for the right place. Always check the plant’s growing conditions before purchasing. A groundcover may thrive in its ideal condition, but struggle in others. Always check botanical names before purchasing since common names can be misleading. It’s easy to confused them with similar non-native species, or a cousin who likes a different microclimate.

Working in the landscape industry, I’ve seen groundcovers planted haphazardly in landscapes with little thought. Use groundcovers to show intentionally, which achieves a certain affect whether it’s for aesthetic or ecological reasons. If you have areas in your landscape that could use some groundcover, consider some of these native choices.

2021 Virtual Wildflower Week Closing Meeting & Thanks!

Thank you to everyone who participated in our 2021 Virtual Wildflower Week! This was a new experience for us hosting a virtual week-long event, but with the help of many people, it was a great success! Special thanks to our website guru Jeff Nelson, our video editor Kendall McDonald, and the iNat extraordinaire Vanessa Voelker!

Here is a recording of the closing meeting on Saturday, May 17th in case you missed it!

The centerpiece of our Wildflower Week was a state-wide BotanyBlitz on iNaturalist from April 10th – April 17th. More than 100 members joined the project and posted over 3,200 observations of Kentucky plants within a one week span! Over 450 different species were photographed. Observations were posted in over 60 counties ranging from Carlisle County in the west to Pike County in the east.

Distribution of iNatuarlist observations from the 2021 KNPS BotanyBlitz April 10th -17th

We also posted virtual field trips throughout the week. If you didn’t get a chance to see them, you can still see them on our website or take a gander at our YouTube channel. The most popular video was by our very own Tara Littlefield, along with her kids Estella and Henry, teaching us about Kentucky Trillium species. Thank you to all those who submitted videos!

We hope you enjoyed this virtual event!
