Kentucky coffeetree, Gymnocladus dioica, is one of the last trees to leaf out in spring but its long brown seedpods persist well into winter when other deciduous trees are bare against the winter sky. Its upright form with ascending branches and rough, ridged bark add to its winter beauty as well.
It grows 60-80 feet high and about 40 feet wide and is tolerant of urban conditions, poor soils and drought. Its name derives from early usage of the seeds as a coffee-like substitute (with no caffeine, and be warned that the seeds are toxic until roasted).
