Native Spotlight: Turk’s cap lily (Lilium superbum)

By Robert Dunlap

In March 2022, I was lucky enough to find a new population of Turk’s cap lilies (Lilium superbum) containing about 500 stems in two colonies in McCracken County while searching for spring ephemerals. Additional searches yielded five more colonies containing another 1,700 individuals, all within about 75 yards of each other.

Due to my unfamiliarity with this plant and the lack of blooms, it took a little research to verify they were Turk’s cap lilies and not their close relative, Michigan lily (L. michiganense). Dichotomous keys usually differentiate between these plants using flower characteristics i.e., tepal curvature and anther length, which is not very helpful if you don’t have a flower to examine. Several online sources mentioned two vegetative characteristics to check: L. superbum has smooth leaf margins (not finely serrate), and the bulbs are white (not yellow). The plants I found exhibited both of these features so I’m going with the Turks cap lily. This plant was found by Mr. Raymond Athey less than 10 miles from this site in 1978, so there is historical evidence supporting the L. superbum identification, as well.

That being said, some botanists are reluctant to rely on the vegetative characteristics described above and feel that positive identification requires examination of flower structures. After being moved to more suitable sites in the future, my hope is that some of these bulbs will produce flowers allowing their identity to be determined beyond any doubt.

The species name is pronounced “superb – um” as opposed to “super – bum” and refers to the flowers, which can be translated from Latin as proud, superb, excellent, splendid, or magnificent. Mr. Linnaeus did a good job naming this plant back in 1762!

Ecology

Turk’s cap lilies are classified as threatened in Kentucky by the Office of Kentucky Nature Preserves and probably occur in less than a dozen counties. They are scattered across the state from Black Mountain in Harlan County in the east to Carlisle County in the west. Threatened plants are defined by the OKNP as “… likely to become endangered within the foreseeable future throughout all or a significant part of its range in Kentucky.” So, the assumption is that their numbers are declining and will continue to do so in the future.

The BONAP map (Biota of North America Project) to the right displays the counties where Lilium superbum occurs in the U.S. Light green counties have stable populations while those highlighted in yellow have populations that are small and possibly declining.

It is generally more common in upland areas along the Appalachian Mountain chain, which includes Black Mountain. So how did they end up in McCracken County and across the Ohio River in southern Illinois? Some botanists have theorized that many southern plant species migrated north and west following the Cumberland River and the Tennessee River, which join up with the Ohio River near Paducah. Perhaps the lilies travelled from the mountains of North Carolina and Tennessee along these waterways over the last several thousand years or so.

Wetland Plant ID Workshops, A Great Success!

By Rachel Cook, EEC

On June 27-29, 2023, the Kentucky Native Plant Society hosted two Wetland Plant ID Workshops at John James Audubon State Park in Henderson, KY. June 27 was a one day workshop for beginners and June 28-29 was a two day workshop for intermediate level participants. The workshops were well attended with 26 participants combined between both workshops, despite some challenging weather.

Participants visited several areas of John James Audubon State Park and nearby Sloughs Wildlife Management area. The workshop instructor, Nathanael Pilla of Midwest Biological Surveys, focused on more difficult taxa such as graminoids and aquatic species. He took students through overarching characteristics of wetland plants, such as unique adaptations for seed dispersal by water and drought tolerance.

Henderson County, where the workshop was located, has been understudied botanically, leading to several new county records being discovered over the course of the three days. These new county records include multiple species of duckweed (Lemna sp.), watermeal (Wolffia sp.), broad waterweed (Elodea canadensis, S3), and joint paspalum (Paspalum distichum). Some other highlights of the workshop were seeing multiple state watch-listed species (S3/S4), including hemlock water-parsnip (Sium suave) and white-nymph (Trepocarpus aethusae).

Workshops are one of the ways the Society fulfills its mission of education about our native plants and native plant communities. Workshops generally are narrowly focused, usually with a single instructor. Most workshops involve a mix of classroom instruction and field work, with an emphasis on hands-on experience for all of the participants. We are already talking about workshops that KNPS might offer in 2024. If there are native plant-related topics that you think would make a good workshop or if you would be interested in presenting a workshop (or know of someone who is), please send us an email at KYPlants@knps.org.

President’s Message – August, 2023

**^{Liz & I enjoying the shade of a massive pecan (Carya illinoinensis) on a hot day at Ballard WMA.}**

Hello fellow native plant enthusiasts. I hope everyone’s summer is going well and that you have been able to get out into Kentucky’s natural areas to enjoy our native plant communities. August is definitely a good news, bad news month. The good news is that many species of native plants are in full flower and the butterflies and other pollinators are taking full advantage of the bounty. The bad news is that August can be brutally hot and humid, making enjoying the extensive blooms a bit difficult. Whenever I can in August, except for those days when the heat index is in triple digits, I brave the heat, get out early, bring plenty of water, find shade when I can, and enjoy the beauty and diversity of Kentucky’s native plant communities. I hope you can as well.

I am absolutely thrilled by the success of KNPS’s two Wetland Plant ID workshops at John James Audubon SP at the end of June. The workshops were well attended with 26 participants, despite some challenging weather. Be sure to read about the workshops and see images from the field, also in this month’s Lady Slipper: Wetland Plant ID Workshops, A Great Success! An enormous thank you has to go out to Rachel Cooke who conceived, planned, and organized this great event. And thanks also to Nathanael Pilla of Midwest Biological Surveys who did such an amazing job of teaching.

Be sure to save the date for the KNPS 2023 Fall Meeting at John James Audubon SP, in Henderson County, on Saturday, October 28. There will be a KNPS member and friends meeting in the morning, with informative talks and updates about the Society. After a break for lunch, there will be hikes, led by experienced botanists and naturalists that know the park, to explore the plants and plant communities that occur at the state park. Along the bluffs of the Ohio River is mature, almost old growth forest with some trees more than 200 years old. Along the Ohio River the 650-acre Audubon Wetlands allows visitors to explore the forest and wetlands of the The Wabash–Ohio Bottomlands ecoregion. This will be the first time since 2012 that one of KNPS’ annual meetings will be hosted in the western end of the state. As a resident of this end of Kentucky, I’m looking forward to welcoming KNPS friends and members from all over the Commonwealth to western Kentucky.

Everything that the Kentucky Native Plant Society does, such as Wildflower Weekend, the Fall Meeting, workshops, field trips, symposiums, and more, happens through the efforts of volunteers giving of their time and creativity. You can help KNPS accomplish our mission, of promoting education about, appreciation for, and conservation of our native flora. If you have ideas for new things that the Society could be doing or thoughts about doing old things better, we want to hear from you. If you want to be more active in areas such as organizing events, leading field trips, helping with membership, writing and editing articles for the Lady Slipper, helping with the website and social media, and more, we want to hear from you. Let us know if you want to help using the comment form below.

Starting this month I am adding a comment form to the bottom of these President’s messages. Please use this form to ask questions, make suggestions, volunteer to help the Society, or just vent if you need to. Your comments will go directly to my email account. Thanks.

Field Trip to Ballard WMA, July 29, 2023

Date of trip: July 29, 2023
Start time: 9AM CDT
Location: Ballard WMW, Ballard Co., KY
Difficulty of hike: Easy. We will car pool/caravan on the gravel roads in the WMA, getting out to walk short distances on flat terrain. Conditions will be hot and humid.

Join KNPS President, Jeff Nelson, 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 drive as a caravan around the WMA, making several stops where we will get out and observe the botany of Ballard’s diverse ecosystems. We will carpool as much as possible to reduce the number of cars in the caravan, but anyone who prefers to drive themselves is perfectly welcome to do so.

We should see several uncommon, wetland plant species. We hope to find Carolina spiderlily (Hymenocallis occidentalis) 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.

There are no bathroom facilities or water available at the WMA. It will be hot and humid. If conditions are such that the heat index will be over 100, we will cancel the trip. We will email you on Friday the 28th if the trip is canceled.

This should be a great field trip with many native species in flower, some that are rare or uncommon in KY. If you have any questions, just email us at KYPlants@knps.org. Register for this field trip using the form below.

Wetland Plant ID Workshops, Space Still Available

[THESE WORKSHOPS HAVE COMPLETED]
Some spaces are still available in both of the upcoming KNPS workshops. There will be both a beginner level and an intermediate level, Wetland Plant Identification workshop at John James Audubon State Park in Henderson, KY on June 27th for the Beginner class and June 28th-29th for the Intermediate class! The workshops are field courses, exploring the Ohio River wetlands and learning how to ID the plants that are found there. The workshops are conducted in sequence and interested parties can sign up for just the Beginner workshop, just the Intermediate workshop, or both. To register for the workshops, use the form at the bottom of this page.

The Beginner Wetland Plant ID workshop will be one day long, on June 27^th, from 9AM CDT – 5PM CDT. The Beginner workshop will cover basic flower structure, leaf arrangement, etc. while highlighting plants as we go. It will be less technical with a focus on demystifying the nomenclature so as to be able to start keying plants out. The instructor will introduce C-values, wetland indicator status, and the basics on how to see the landscape in a broader, phytological way. There is a $25 registration fee for this workshop.

The Intermediate Wetland Plant ID workshop will be held over two days, June 28-29^th, from 9AM CDT – 5PM CDT each day. This workshop is aimed towards individuals with some prior experience in field identification of wetland plants and will focus on how to identify more complicated genera and groups (i.e. graminoids and asters). An understanding of basic floral morphology (petals, sepals, tepals, stamens, etc.) is more or less expected. We will be looking at keys and getting a bit deeper in the descriptive elements of the flora.In addition to Audubon State Park, there may be a visit to other close natural areas. There is a $75 registration fee for this course.

Courses will take place from 9am-5pm CDT each day and have a 1-hour break for lunch (bring your own lunch). You will need to bring a notebook, loupe or hand-lens, phone or camera, pencils, and preferred reference book if you’d like. Remember that these are field courses and may get into wet areas, so please wear appropriate clothing and bring water.

If you have any questions, email us at KYPlants@knps.org

Field Trip to Lilley Cornett Woods, June 17, 2023

Date of trip: June 17, 2023
Start time: 10AM EDT
Location: Lilley Cornett Woods, Letcher Co., KY
Difficulty of hike: Medium difficulty, approximately 1.5 miles

Join us for a hike at one of the most notable natural areas in Kentucky and a registered national landmark, EKU’s Lilley Cornett Woods. Located in Letcher County, Lilley Cornett Woods is an old-growth forest, a forest that has not undergone any man-made changes in 150 years. During your hike LCW guides will provide you with an educational experience on various topics ranging from the 12 characteristics of old growth, mixed mesophytic forest, diverse flora and fauna native to Appalachia, and most notably LCW’s incredible “big trees.”

The Shop Holler trail is LCW’s shorter trail at approximately 1.5 miles with medium difficulty. Plan to be on the trail for about 3 hours with the guide, while you traverse the mountainside through different forest communities. This is LCW’s most popular trail due to its shorter length, but don’t be fooled, you will be amazed by the diversity of the area and be able to truly understand a mixed mesophytic forest.

No pre-registration is required for this hike. You will meet, register, and sign waivers at the Visitors Center. From the parking lot the Visitors Center building is on the hill, up the sidewalk. Hike leaders will be outside the Visitor’s Center waiting for you.

Lilley Cornett Woods is located at 91 Lilley Cornett Branch, Hallie, KY. Driving Directions.

KNPS 2023 Fall Meeting, Save the Date, Oct. 28

^{John James Audubon SRP, Oct 26 2022, photo by Haley Owens}

Save the date for the KNPS 2023 Fall Meeting at John James Audubon SP, in Henderson Co., KY, on Saturday, October 28. There will be a KNPS member and friends meeting in the morning, with informative talks and updates about the Society. After a break for lunch, there will be hikes, led by experienced botanists and naturalists that know the park, to look at the plants and plant communities that occur at the state park.

John James Audubon State Park is located just south of the Ohio river in Henderson County in western Kentucky. The park preserves the peaceful woods where John James Audubon walked as he studied the subjects of his paintings. The park museum features the largest collection of original Audubon art in the world in addition to personal artifacts about his life.

The surrounding forest along the bluffs of the Ohio River is mature, almost old growth in nature with some trees more than 200 years old. Approximately half of the property has been dedicated as a state Nature Preserve. At least 61 species of trees and more than 200 wildflowers have been documented from the site. The north facing, mesic forests are dominated by American beech, sugar maple, and American basswood whereas the more south facing slopes are dominated by sugar maple, various oaks, and tulip tree. At least 169 bird species have been observed in the park.

The 650-acre Audubon Wetlands was added to the park by the Kentucky Heritage Land Conservation Fund in 2016. There are bald eagles nesting and a heron rookery, as well as habitat for waterfowl and amphibians. The Friends of Audubon, a local nonprofit, has installed a wheelchair accessible boardwalk through the wetlands with plans to install more.

We have just begun the planning process for the 2023 Fall Meeting. If you have any thoughts, suggestions, or questions, email us at KYPlants@knps.org.
