An accent or specimen shrub in moist locations.
Ecological Restoration Notes:
A rather rare element of a variety for upland ecosystems.
Grown by several native plant nurseries in central and northern Florida.
Medium to large erect woody shrub with sparse foliage and upright stems that ultimately bend toward the ground.
Typically 4-12 feet in height. About as broad as high and often growing in clumps.

Moderate; can grow in nutrient poor soils, but needs some organic content to thrive.
Salt Water Tolerance:
Low; does not tolerate long-term flooding by salt or brackish water.
Salt Wind Tolerance:
Moderate; grows near salt water, but is protected from direct salt spray by other vegetation.
Moderate; generally requires moist soils, but tolerant of short periods of drought once established.
Full sun to light shade.

Wildlife and Ecology:
Provides significant food and moderate amounts of cover for wildlife. Larval host plant for silver spotted skipper (Epargyreus clarus) and southern dogface (Zerene cesonia) butterflies.
Can be grown from seed, cuttings, air layers and suckers. Seeds should be sown as soon as they are ripe. Greenwood cuttings are best in early summer, hardwood cuttings in the fall.
