It’s easy to see the common partridge pea (Chamaecrista fasciculata) flowers this time of year. If you look carefully, you can find its smaller relative, the sensitive partridge pea (Chamaecrista nictitans).
Common partridge pea flowers are about one inch wide. The flower petals are about the same size. The sensitive partridge pea flowers are less than half an inch wide, with the bottom petal being larger than the others. The flower of the sensitive partridge pea does not fully open. Both plants have sensitive leaves that fold closed when you touch them. Give it a try!
I’ve found the sensitive partridge pea in shady areas, and the common partridge pea in open, sunny areas.
Let me know when you see them!
