The most popular species is triacanthos, the Honey Locust, a really handsome deciduous tree of the Pea order (Leguminoseae), up to fifty feet high, with greenish flowers in July. The foliage is beautiful. A garden form called excelsa pendula is offered. Sinensis (syns. horrida and ferox) is also met with, and is remarkable for the large clusters of formidable spines on the stems and main branches; a drooping form called pendula is offered and there are others. Height up to twenty-five feet, greenish flowers in early summer. Ordinary soil. The garden forms are grafted on to the species.
See Willow and Salix.
A rare genus. Lasianthus and pubescens, both white-flowered, are nominally hardy, but owing to the non-ripening of their late growth in the often sunless autumns of Great Britain, they are frequently injured. They need a sunny spot, but a cool, moist, yet well-drained soil. Both are beautiful and worth an effort on the part of connoisseurs, especially those who enjoy grappling with difficult subjects.
