Description
Common Name: rayless sunflower
Helianthus radula is a perennial herbaceous species.
Distribution
Ecology
Habitat
H. radula can live in loblolly or slash pine communities,[1] upland longleaf pine communities, [2][3] pine-oak sandhill woodlands, near the edges of bogs, limestone glades, and mixed oak-cabbage palm hammocks (FSU Herbarium). Additionally, it occurs in disturbed areas such as roadsides, old fields, power line corridors, by trails, and in lawn and waste areas (FSU Herbarium). This species seems to prefer semi-shaded areas, and occurs on mostly wet to dry sandy soils, or over limestone (FSU Herbarium).
Phenology
Flowering and fruiting has been observed in August through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species has been found in habitat that is burned frequently (FSU Herbarium), even biennially.[3]
