I live in a high desert region. Last year I decided to go green and add groundcover plants that do not need to be watered as often. Thyme plants thrive in sunny locations. I love the fact they rarely need water or fertilizing. They aren't picky about soil either--dry, gritty soil is fine. Thyme is hardy and some varieties can tolerate the snow and freezing temps we have in Colorado. The thyme plants vary in height. The one pictured here only grows to approximately 3-5 inches high and slowly spreads to 24 inches. This is the perfect height because I can walk through the garden without accidentally stepping near a rattlesnake or two! Best of all, the fragrant green carpet smells wonderful.
