- Description
-
Trifolium reflexum or Buffalo Clover is a North Carolina native perennial in the bean family. A rare plant that was once abundant, it has seen a strong decline in the past few decades. In North Carolina, it has been given a State Threatened status. On the rare occasions that it is located, it is seldom in large stands. It tends to become shaded out by taller species as well as declining for no apparent reason.
Its natural habitat includes open woodlands, woodland edges, and other dry shady locations. While wildfires may damage some plants, prescribed burning in some locations have stimulated the germination of pre-existing seed banks as well as creating an ideal seedbed for the seeds to establish themselves.
It is often confused with Trifolium pratense (Alsike Clover). One distinguishing feature is the flower head of Buffalo Clover sits well above the leaves, where the head of Alsike Clover appears to be resting on the leaves. Also, during and shortly after flowering, the lower portion of the flowers of Buffalo Clover hang downward or droop. This gives the flowers a two parted cluster, an erect top and a drooping lower half, leading to the botanical identification of reflexum.
