- Description
-
David's mountain laurel, is a spiny, deciduous shrub in the Fabaceae (bean) family native to southwestern China and typically grows to 6 to 8 feet in length and width. The genus name Sophora is Arabic and the species name davidii is in reference to Jesuit missionary ean Pierre Armand David (1826-1900).
It grows best in rich soil or well-drained sandy loam, with medium moisture, in full sun or partial shade. It also does well in clay soil, but it will not grow in the shade. In spring, it displays small, fragrant ,and showy blue and white blossoms that are more prolific if the plant is sited in full sun and protected from cold winds. The plant's foliage is also quite attractive. Once mature, the plant tolerates heat and some drought. Propagate the plant by scarifying the seeds.
The thick dense canopy of leathery leaves and spiny branches makes it ideal for use as a hedge or security plant in the landscape. This low-maintenance shrub is noted for its ability to fix nitrogen within the plant.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. Twig blight, verticillium wilt, canker, powdery mildew, and rust may occur. The seeds are poisonous.
