Discussion

Dirca decipiens occurs typically in more xeric sites than D. palustris and is frequently associated with Quercus and Juniperus. It is currently known from only four populations.

Flowers of Dirca decipiens appear about one week after those of nearby populations of D. palustris. The plants are relatively quick growing in cultivation and seed germination rates appear to be much higher than in other Dirca species. The leaves are parasitized, likely by Leucanthiza dircella Braun (Lepidoptera: Gracillariidae).
