Penthorum sedoides L.
Common Name: DITCH STONECROP

Coefficient of Conservatism: 3
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

Wet ground, ditches, marshes, borders of streams and ponds. Quite variable in stature, ranging from unbranched stems only a few centimeters tall to bushy branching plants over half a meter tall. Unlike any other species in our flora: the apetalous flowers are cream-colored, but as the carpels ripen into a star-like fruit (a cluster of follicles united at the base) they become quite red. The branches of the inflorescence are glandular-hairy, ± curved, with flowers on the upper sides.
