Description

A description of Helianthus radula is provided in The Flora of North America.

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). Associated species include Pinus palutris, Quercus laevis, Serenoa repens, Sabatia brevifolia, Kalmia hirsuta, Balduina uniflora, Polygala lutea, Sorghastrum secundum, Quercus pumila, Seymeria cassioides, Liatris graminifolia, Helianthus heterophyllus, Cirsium, Bigelowia, Ludwigia, Pinus elliottii, Pityopsis, Baptisia simplicifolia, Ilex glabra, Andropogon, Rynchospora, Phoebanthus tenuifolia, Eupatorium album, Pityopsis, Rhexia alifanus, Liatris gracilis, Carphephorus odoratissimus, Baptisia simplicifolia, Ctenium aromaticum, Vaccinium darrowi, Quercus pumila, Quercus minima, Gaylussacia dumosa, and Physostegia godfreyi (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]

Pollination

Use by animals

Diseases and parasites
