Status

Maryland has both native and non-native species of Sedum sensu strict. Some of the 'stonecrops' found in Maryland are assigned to other genera (see Crassulaceae). Many species in this genus are cultivated for house plants, for rock gardens and for green roofing projects.

Description

To identify species of Sedum it is important to observe the leaf shape and leaf arrangement (whorled vs. alternate). It is also important to note whether the flowers or fruits have 4 or 5 parts. The most common native species - Sedum ternatum - has spatulate leaves in whorls of 3 or 4; and flowers that are 4-merous.

Where To Find

The native species of Sedum are typically found in moist forests, steep slopes and on rocky outcrops. The non-native species may also be found on rocky outcrops but are more frequently found in disturbed urban and suburban habitats.
