Groundcovers in the Xeric Garden
Groundcovers are the flowering carpets of our gardens, acting as a living mulch to shade the soil, holding the soil in place on slopes and providing flowers for pollinators when they’re in bloom. A well designed garden uses groundcovers to edge pathways to soften the edges, planted between flagstone to help color-up expanses of flat rock and to soften the borders of raised beds when they cascade over the edges. And groundcovers are excellent to plant bulbs and taller growing perennials into. Wooly thyme and wildflower tulips make a wonderful spring combination. Hardy Plumbago and Salvia greggii cultivars provide nectar and refreshing flower color combinations in late summer and early fall.
This large growing Ajuga has huge blue flower spikes in late spring/early summer that bees love as a nectar source. This is a shade lover and is very useful for planting under pinon and other trees and large shrubs that cast shade. Ajuga likes regular irrigation to keep it happy and growing vigorously.

The first cold hardy ice plant to be introduced in North America, this South African succulent is an outstanding groundcover renowned for its summer-long display of large purple, honeybee attracting flowers. It makes a great groundcover for covering gravel mulch to reduce glare and reflected heat. But if rabbits are a problem, this is not a good choice unless protected in courtyards and other fenced areas. Full or part sun. 24-24" tall x 24-36" wide and cold hardy to zone 4.
