Trifolium kentuckiense

Trifolium kentuckiense is a critically imperiled species of clover endemic to the U.S. state of Kentucky. It is commonly known as Kentucky clover. It is found only in Franklin and Woodford counties in Kentucky and is considered to be highly endangered.

It is similar in appearance to non-native Trifolium pratense, but can be distinguished before blooming by longer petioles and lack of pubescence (hairs) on the upper surface of the leaf. Unlike related species Trifolium reflexum, it grows best in highly basic limestone soils.
