Sophora secundiflora (Texas Mountain-Laurel) is a large shrub or small tree native to Texas and northern Mexico. It can grow up to 5-10ft tall or 10-20ft as a tree. It is recommended to plant it in full sun or semi-shade areas, and needs moderate water. Sophora secundiflora blooms fragrant, violet, blue and lavender flowers from February to April. These flowers attract butterflies and hummingbirds. The seeds contain alkaloid cytisine, making them poisonous or toxic.
When taken care of properly, this plant can be cold hardy at least to temperatures in the upper 20s F for a short period of time. It is generally grown in USDA Zones 8-10. When grown in a pot, Sophora secundiflora should be in a well-drained, alkaline soil and be kept on the dry side, especially when blooming. Ethnomedical uses of the Sophora secundiflora include the treatment of digestive and respiratory complaints, colds, and rheumatism.
