Dichanthelium sphaerocarpon is a perennial graminoid.

Distribution

Ecology

Habitat

Dichanthelium sphaerocarpon occurs in a variety of natural and disturbed communities. It is abundant in barrens habitats[1], but also occurs in pine-oak flatwoods and woodlands, mixed hardwood floodplains, pine forests, cabbage palm hammocks, and on loessial banks, the edges of open brackish marshes, and sand dunes (FSU Herbarium). It is also able to grow in disturbed areas, especially in higher light levels (FSU Herbarium). D. sphaerocarpon has been found in power line corridors, clear-cuts, roadsides, ditches, firebreaks, and old fields (FSU Herbarium). This species seems to prefer sandy or loamy soils, but can tolerate a range of moisture levels, from dry to wet (FSU Herbarium).

Phenology

Flowering and fruiting has been observed in Florida in February through November (FSU Herbarium).

Seed dispersal

Fire ecology

It increased from absent to 19 plots within the span of six years after an early dormant-season fire in 1989 at Gibbons Creek Barrens.[1]
