Black Dalea is a rare fall-blooming groundcover blanketed from late-summer to fall with purple flowers that attract butterflies and quail to your garden. Its fine-textured foliage of tiny leaflets contrasts nicely with cacti, yuccas, and succulents. This extremely drought-tolerant, fairly fast-growing shrub requires little or no maintenance. Black Dalea resents fertilizer and overwatering, which promote weak growth; it can tolerate light, filtered shade, but may get leggy with too much shade. Since it drops most of its leaves during its winter dormancy, place it near evergreens or succulents to avoid an obvious “hole” in your winter landscape. Shear it fairly hard in late winter to rejuvenate the plant. Pollinators, including bees, love the flowers, so avoid planting close to areas where people gather. Excellent for erosion control on slopes, as a low-maintenance groundcover, an accent plant, and where reflected heat may be too much for other plants.
