Dalea greggii, or trailing indigo bush, is a low-water-use, mounding plant that makes a great groundcover. Native to the extreme conditions of far West Texas, Dalea will struggle in heavy soil and does not take kindly to being overwatered. It’s evergreen, but responds well to a light shearing in late winter, before it puts on new growth and tons of small, deep purple flowers. Trailing indigo bush normally mounds to about a foot tall and spreads to about four feet, and if you’ve got a steep slope with poor soil, this is the plant for you.
