Ditch stonecrop is native to North America; its range includes the majority of the states in the U.S. and the provinces in Canada. It is a small (1-2' tall) plant with green or red stems, usually unbranched. Cymes of flowers 1-3" across arise from the upper stems, each cyme with 2-4 spreading flowering stalks; flowers are restricted to only one side of the flower stalks. Individual 1/4" flowers are yellowish-green to white, have five spreading, green sepals, ten stamens with cream-colored or yellow-orange anthers, and five beaked carpels, each with a single style and a green stigma; petals are completely absent. (The carpels look rather like a teapot with no handle and a very wide spout, or like a "duck" wine decanter. Look it up.) The carpels become the seed capsules; they turn bright red when mature. Ditch stonecrop prefers wet habitats (like ditches). It is completely unrelated to biting stonecrop (Sedum acre).

About

I want to acknowledge the work of a friend and colleague, Dr. Fred Donner. We both share a passion for the flowers in Jackson Park. Fred's website (jacksonparkwildflowers.org) inspired me to build my own website and database; use and enjoy them both.

I am also pleased to thank my ninja web gurus and coders, Lindsey Young and Stefanie Engstrom. This site would not exist without their herculean labors.
