Erythrina (from Greek for red). Leguminosae. Coral-tree. Herbs, shrubs or trees, with large and showy papilionaceous flowers, for planting out and for greenhouse bloom; and open-ground subjects in Florida and California.
Erect, or the herbs more or less reclining, usually spiny: Lvs. alternate, pinnately 3-foliolate, with small glanduliform stipules: fls. mostly red and in dense racemes; calyx 2-lipped or oblique; standard free or very nearly so, erect or spreading; tenth stamen free, or united only half its length: fr. a slender, more or less twisted pod; seeds mostly ovoid.—Known species about 50, in tropical and warm temperate regions around the world.
Erythrinas are much prized garden plants. Some of them, particularly the herbaceous kinds, are frequently planted out in the summer. In the house they demand an intermediate temperature. Give rich soil and frequent waterings. In the woody species, aim to have well-ripened wood for flowering, for the bloom is produced on wood of the preceding year. The herbaceous species are propagated by division of the rootstock; also by cuttings from shoots springing from the old roots. Woody species are propagated by cuttings of growing wood. All species are propagated by seeds, whenever these are obtainable. Many species have been more or less grown or tried within the limits of the United States; some of them fail to bloom in southern California, probably because of insufficient summer heat. The forms more or less in cultivation are likely to be imperfectly or doubtfully determined botanically. Some of the erythrinas arc used as shade for coffee and cacao plantations.
Herbaceous species (or treated as such). These die down at the end of the season, and the roots may be stored after the manner of dahlias. It is best to start the roots before planting them out, particularly in the N. In their native countries, these species are more or less woody. CH
