Trailing indigo bush (Dalea greggii) DAY-lee-ah GREG-ee-eye Genus:  Dalea Despite a soft, delicate appearance, trailing indigo bush is one of the toughest groundcovers around. The feathery, silvery green compound foliage makes the clusters of tiny, rosy purple flowers stand out at close range. The blooms, which occur most heavily in spring and summer, return sporadically the rest of the year. This plant is excellent for stabilizing soil on slopes because its stem nodes root wherever they come in contact with the ground. Noteworthy Characteristics:  Trailing indigo bush is a tough, attractive groundcovering plant that is native to the Southwestern U.S. Care:  Grow in full sun and well-drained soil. It likes reflected heat. Problems:  Infrequent.
