Sophora secundiflora syn. Dermatophyllum secundiflorum

A special and rare purple-blue flowering plant for enthusiasts and those who love variety.

Mescal bean or Texas mountain laurel is an evergreen, usually multi-trunked shrub or small tree ranging from just a few feet tall to more than 9m in height, though its usually much less, especially on poor soils. The dense, dark green, and glossy compound leaves.  The bluish lavender fragrant flowers, are in showy clusters. The pod is like our native kowhai but with bright red poisonous seeds.

Found in Mexico and southern Texas. Hardy to -10 evidently. My little plants suffered in the frost outside last winter.
