April - May Also called eastern redbud and Judas tree. Usually found along woodland margins, often in the shade of other trees. Found in the east half of Kansas.
Flowers appear before the leaves, in clusters along braches of the previous year's growth.
The fruits remain on the tree until early winter. Infusions made from the bark were used to treat fevers, congestion, whooping cough, and vomiting. Eastern redbud is the state tree of Oklahoma.
