Availability:
	Rarely grown by native plant nurseries.
Description:
	Trailing or twining vine with delicate stems.

Nutritional Requirements:
	Low to moderate; it can grow in nutrient poor soils or soils with some organic content.
Salt Water Tolerance:
	Low; does not tolerate flooding by salt or brackish water.
Salt Wind Tolerance:
	High; can tolerate moderate amounts of salt wind without significant injury.

Wildlife and Ecology:
	Larval host plant for long-tailed skipper (Urbanus proteus) and northern cloudywing (Thorybes pylades) butterflies. Attracts bee pollinators.
Horticultural Notes:
	Can be grown from seed. The pods will open and eject the seeds when completely ripe, so collect pods when mature and store in a paper bag until they open.
Comments:
	Forms in Miami-Dade and Monroe counties have narrow leaflets, and are segregated by some authors as C. angustifolia; forms to the north and west have broad leaflets. Appropriate sources of material should be used. See also the Florida Wildflower Foundation's Flower Friday page.
