If a plant is needed to cover an area in full sun, in almost any kind of soil, and that is going to be neglected (no water, no mulch, no fertilizer, no weeding around it), this is the perfect plant.

A very pretty Thyme. It transplants well and grows fast. I think it looks nice year round. My information says that it is hardy in zones 4-9. Blooms in July in my garden.
