Description

"Perennial herb, 0.6-1.2 m tall (or shrub or tree up to 8 m high further south) with usually prickly brachlets. Leaves pinnately 3-foliolate; leatlets thinly chartaceous, glabrous, or nearly so, throughout, occasionally pricky beneath, hastately 3-lobed to widely deltoid, (2) 4-8 (12) cm long, stipellate. Inflorescence terminal, much elongate on usually leafless stems arising from the crown, (1) 3-7 dm long with few to numerous, papilionaceous flowers; pedicels 3-9 mm long, subtended by linear- lanceolate bracts 1-4 mm long and with 2 liner, caduceus bractlets, 1-2 mm long. Calyx glabrous, or nearly so, tubecampanulate, truncate, 5-11 mm long; the standard scarlet, 3-5.3 cm long, wings 5.5-11 mm long, keel 6-13 mm long; stamens diadelphous, 9 and 1; stigma capitate, ovary and stipe pubescent. Legume 7-15 (21) cm long, 1.2-1.6 cm broad, constricted between the several to many, scarlet seeds, stipe 1.5-4.5 cm long." [1]

Distribution

This species is generally distributed from southeast North Carolina south to Florida, west to southeast Texas, and south into eastern Mexico.[2]

Ecology

Habitat

General habitats of E. herbacea includes dry sandy woodlands, maritime forests, and sandhills within the outer Coastal Plain region.[2] It occurs in sand pine woodlands, sandy hills, along edges of sinkholes, live oak-cabbage palm forests, uplands, hammocks, flatwoods, sand pine scrub, pine-palmetto scrub near ocean, longleaf pine-wiregrass savannas, shaded slopes of river bluffs, and in calcareous open prairies. Found in disturbed areas such as along roadsides, in understory of recently clear cut pine woodlands, and edges of woodlands. Can thrive in areas that are shady, semi-shady, or open. Is associated with areas that have sand soil types, sandy loam, loam, thin loamy sand, and calcareous soil types.[3]

Associated species include Quercus geminata, Q. chapmanii, Q. incana, Osmanthus megacarpus, Ilex ambigua, Vitis rotundifolia, Serenoa repens, Persea, Myrica, Carya glabra var. megacarpa, Pinus palutris, Baccharis halimifolia, Rhus copalina, Callicarpa americana, Diospyros virginiana, Morus.[3]

Phenology

E. herbacea generally flowers from May until July.[2] It has been observed flowering from February to June with peak inflorescence in April and May, and fruiting from April to August.[3][4]

Seed bank and germination

Seeds germinate easily when scarified.[5]

Fire ecology

Is associated with annually burned pinelands.[3]

Pollination

Hummingbirds drink the nectar and pollinate E. herbacea.[5]

Use by animals

It is a nectar food source for hummingbirds. This species has toxic seeds for humans, which are used in Mexico for poisoning rats and various fish; the seeds are also made into novelties and necklaces which should be kept away from children.[5]

Conservation and management

For general management, dead stem tips should be trimmed once new growth emerges in the spring when frost damage is visible.[5]
