Trailing Indigo Bush
Trailing Indigo Bush is definitely one of the most successful groundcovers used in the Southwest. This low-growing, evergreen has the ability to form roots wherever its stems touch the ground, making it an excellent soil stabilizer, and enabling it to rapidly spread 6-8 feet or more while maintaining a mounding height of only 2 feet. If left unchecked, Trailing Indigo Bush will form a dense, rolling carpet over harsh, rocky areas and banks, where it can survive on as little as 11 inches of rainfall a year. In spring, small purple blossoms appear in abundance, attracting butterflies but doing little to change the calming effect of the plant’s soft and finely-textured, grey-green foliage.
