Description
A description of Silphium asteriscus is provided in The Flora of North America.
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. asteriscus can be found in red oak/mockernut woods, sandy hillslopes, mixed hardwoods, upland pine forests, longleaf pine forests, annually burned pinelands, deciduous woods, upland oak-pine woodlands, pine flatwoods, calcareous outcrops, and longleaf pine-deciduous live oak flats. [1] In disturbed habitats it can be found in cutover upland longleaf pine savannas, along highways, along roads, and sandy fallow fields. Soil types include loamy sand, sandy loam and clay. [1] It has been observed to grow with Polymnia. [1] Associated species include shortleaf pine, post oak, red oak, mockernut hickory, longleaf pine, live oak, loblolly pine, and a Polymnia species. [1]
Outside of the Coastal Plain, it can be found in the Cross Timbers in wooded-open ecotones of oaks, ashes, elms, and hickories [2] and the Midland Plateau Central Highlands where the surface soil texture is sandy clay loam and clay subsoil. [3]
Phenology
S. asteriscus is a perennial species; stems have prickly hairs and can grow up to five feet high. The lower leaves are alternate and the upper are opposite and sessil. The flowers are yellow and have nine florets in the ray. [4] Kevin Robertson has observed this species flower within three months of burning. KMR
Fire ecology
It resprouts and flowers within two months of burning in the spring (Robertson observation).
Use by animals
It is included in white-tailed deer diets in Cross Timbers ecosystem in Texas. [2]
In the Cross Timbers ecosystem of Texas, it has been found in white-tailed deer diets. [2]
