General Landscape Uses:
Primarily recommended for natural landscapes and habitat restorations. Also wildflower and butterfly gardens.
Ecological Restoration Notes:
A relatively common element of pinelands and open, coastal uplands.
Grown by enthusiasts.
Trailing or twining vine with delicate stems.
N/A; a vine with stems to 6 feet or more in length, but often shorter. Sometimes spreads and forms small open patches.

Pinelands and coastal uplands.
Moist, well-drained sandy or limestone soils, with or without humusy top layer.
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:
Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
High; does not require any supplemental water once established.
Full sun to light shade.
Purplish lavender to nearly white, about 1" long.
All year; peak summer-fall.
Flat pod (legume).
Wildlife and Ecology:
Larval host plant for long-tailed skipper (Urbanus proteus) and northern cloudywing (Thorybes pylades) butterflies.
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.
Forms in Miami-Dade and Monroe counties have narrow leaflets; forms to the north and west have broad leaflets. Local sources of material should be used.
