Description
Distribution
A. curtissii is an endangered perennial that is endemic to the Florida scrub in the central and southern peninsula (Mondo et al. 2010; Wunderlin and Hansen 2011).
Ecology
Habitat
In the Coastal Plain in Florida, A. curtissii can be found in scrubs (FSU Herbarium; Weakley 2015; Wunderlin and Hansen 2011) with Quercus myrtifolia, Q. chapmanii, Lyonia, Ilex, Selaginella, Lechea, pines and palmettos (FSU Herbarium). It has also been found in recently bulldozed low ancient scrub.
It has been observed to grow in close proximity to woody vegetation and unlikely to be fond in open gaps due to seed germination being enhanced by shade and not leaf litter (Mondo et al. 2010). Seeds planted in shaded areas among other shrubs have a higher rate of germination compared to seeds planted in open gaps (Mondo et al. 2010).
Phenology
It flowers from spring to summer (Wunderlin and Hansen 2011). Michelle Smith observed Asclepias curtissii flowering August 2015 at the Jupiter Inlet Lighthouse Outstanding Natural Area (Nature Preserve) in Tequesta (Palm Beach County), FL.
Seed dispersal
Seed bank and germination
Fire ecology
The Nature Preserve in which Michelle Smith observed this species flowering, the Jupiter Inlet Lighthouse Outstanding Natural Area in Tequesta (Palm Beach County), FL., has conducted prescribed burns in the past as part of the restoration project for this area, where the BLM and other organizations are part of PCB.gov
Pollination
The following Hymenoptera families and species were observed visiting flowers of Asclepias curtissii at Archbold Biological Station (Deyrup 2015):
Halictidae: Lasioglossum nymphalis
Use by animals
Diseases and parasites
Conservation and Management
Cultivation and restoration
