Description
Sorghastrum secundum is a monoecious perennial graminoid[2] that grows to 3-6 feet (0.91-1.83 m).[3]
Distribution
S. secundum occurs from southern South Carolina, south to southern Florida, and westward to southern Alabama.[1]
Ecology
Habitat
This species is found on sandhills.[1]
Phenology
Flowering occurs in September and October[1] and germination seems to peak in January and February.[4]
Seed bank and germination
In south Georgia, S. secundum buried in seed bags had a 26% germination rate after one year, 34% after two, and 9% after four.[4]
Use by animals
S. secundum consists of 2-5% of the diet for terrestrial birds.[5]
Diseases and parasites
Its seeds are more prone to mold destroying it prior to germination compared to other seeds.[4]
