Agaves are striking and architectural Southwest native plants and are included in a group of plants I term Southwest evergreens. They are unusual in that at maturity, they only flower once, and then die. for this reason, some classify them as multiannual, rather than perennial. However, as they common name suggests, it takes many years before they flower. Leaves of the Agave are arranged in a spiral beginning from a near invisible stem, forming a rosette.Agaves vary in size from 4-6 inches to larger than man-size.

The only draw back to this pretty, silver-edged groundcover is its flowers! If only it didn’t, it would be a perfect no maintenance, no water groundcover for hot, sunny locations.

Though a creeping groundcover, silver-edged horehound is not invasive like the common horehound, M. vulgare.

Nandina is one of a few single species genera, a member of the barberry family (Berberidaceae). Though one species, several cultivars are available to add texture and interest to our low maintenance, low water-use landscape in either sun or shade. I plant mine in full shade, as there are few shrubs that will flower there. I personally favor protecting Nandina with afternoon shade, if planted in a sunny location.
Junipers are native to much of the U.S. and come in many sizes and shapes. Juniperus horizontalis is the low growing and spreading juniper, used mainly as an evergreen groundcover.

Sedum groundcovers spread nicely in a low to medium water use area of gritty, well drained soil, and will do just fine in afternoon shade.
Mahonia repans is one of my favorite plants with four seasons of interest. Low growing and spreading evergreen shrub is native throughout the Rocky Mountains. Bright yellow berries in spring are followed by black berries in summer and reddish winter foliage. The leaves are thick, glossy and holly shaped.
