Erythrina lysistemon aka Common Coraltree

Erythrina lysistemon belongs to the pea family, Fabaceae. Its common names include lucky bean tree and common coral tree. Its native range runs from Tanzania south to South Africa. It grows in dry scrub, bushland, and wooded grassland. It also occurs in deciduous woods and on coastal dunes. These habitats span low ground to 6,398 feet [1,950 metres].

This prickly tree sheds its leaves and forms a spreading crown. Branches often start low on the trunk. Its usual height range is 7–39 feet [2–12 metres]. Some trees reach 66 feet [20 metres]. The source also gives 33 feet [10 metres] as a reference height. Flowers appear before the new leaves emerge. This display is a main reason people plant it. Birds and insects pollinate the flowers, and the species is self-fertile. Its red seeds have been used to make necklaces.

It grows best where frost does not occur. A sheltered tree may survive brief cold spells down to 19°F [−7°C]. Young plants need protection from frost. Dry winters suit it best, though wet winters need not rule it out. Good soil drainage matters where winters are moist. Established trees can withstand some drought, but grow better with moist soil. It resembles the coast coral tree, Erythrina caffra. The two can be hard to tell apart without flowers.

People grow it as a garden tree and street tree. Its prickles also suit hedges and barrier plantings. The dry wood is light, with a cork-like texture. People have used it for canoes, rafts, and fishing-net floats. Other uses include troughs, brake blocks, and roof shingles. Tar treatment helps the wood last when used for roofing. Wild trees also supply materials for local use.

Traditional medicine uses its bark, leaves, and roots. Reported uses include dressings for wounds and preparations for earache or sprains. These records describe past use, not proof of safety or benefit. The source lists no known edible uses for this species. It also lacks species-specific measurements of its toxic alkaloid content. Seed propagation calls for warmth, moisture, and a free-draining potting mix. Overnight soaking may speed germination, but is not essential. Cuttings provide another way to raise new plants.
