Name: Sedum pulchellum Saturated Herbaceous Alliance Reference: Southeastern Ecology Working Gro... Description: This alliance consists of shallow-soil glades of the southeastern United States. Sedum pulchellum is characteristic, and it often forms dense mats. In addition to Sedum pulchellum (which has been characterized as being annual, biennial, or perennial), the vegetation consists largely of annuals (Leavenworthia) or nonvascular plants (e.g., Nostoc, a blue-green alga or cyanobacterium). Talinum calcaricum is actually a perennial. In Arkansas examples, herbaceous associates include Croton willdenowii, Plantago aristata, Coreopsis lanceolata, Agrostis elliottiana, Danthonia spicata, Hordeum pusillum, and Ruellia humilis. Vernal pools or depressions in the substrate which hold moisture play an important role in the dynamics and persistence of this vegetation. In Tennessee and Texas, this alliance occurs over limestone or glauconite; in Arkansas, it occurs over shale.  Accession Code: VB.CC.19043.SEDUMPULCHELLUM Plot-observations of this Community Concept: 0
