Another site is on an abandoned railroad embankment. New basal rosettes are also produced at the ends of short lateral rhizomes or roots. Germination dates are unknown, possibly occuring in summer. Anthesis occurs in November and primarily in December. The reproductive phenology of this species appears to be similar to, but somewhat later than, that of the closely related, ubiquitous Chrysopsis scabrella.
Pollen is disseminated by insects.
The entire genus has out-crossing breeding systems. Seed dissemination is probably effected only by gravity. No information is available. Both species are perennial. C. floridana is usually found on St. Lucie Fine Sand or Lakewood Fine Sand.
