Polk County’s Most Wanted – Kidneyleaf Twayblade
Have you seen Kidneyleaf Twayblade?
In a joint effort to expand the knowledge and understanding of the flora and fauna of Polk County, Conserving Carolina and botanist/ecologist David Campbell need your help in locating this month’s “Polk County’s Most Wanted—Plant,” a cryptic and enigmatic orchid of the mountains- the Kidneyleaf Twayblade (Listera smallii).
What does it look like?
Always under twelve inches in height, this orchid has two opposite, dark green leaves that are wider than long. It produces up to 15 unique-looking flowers that are combinations of white, brown, purple, or green. Flowers are 1/4” – 3/8” long with two divided and spreading rounded lobes.
Where should I look for Kidneyleaf Twayblade?
Occurring exclusively in the southern and central Appalachians, the Kidneyleaf Twayblade (sometimes referred to as the Appalachian Twayblade) is one of our lesser known orchids. Found in mountainous regions in our state, preferred habitats are in the acidic humus of shaded swamps or damp thickets with Rosebay Rhododendron (Rhododendron maximum). Bloom times in our region are June and July.
Although not yet reported for Polk County, Kidneyleaf Twayblade should be purposefully searched for in the western, montane section of the county. Look carefully in deep shade, close to a stream or other water source and under Rhododendron maximum. Populations are not typically large and the plant’s coloration makes it easy to miss.
What can you do?
