Houstonia serpyllifoliaAlso known as:
This groundcover has tiny, thyme-like leaves. Once established, Houstonia serpyllifolia will create a moss-like, bright green carpet. The diminutive flowers may be white to violet, are made up of four petals and radiate from a yellow center. Established colonies will bloom profusely.
The growing habit of the thymeleaf bluet make it well suited for shade gardens, shaded rock gardens and in front of borders, so long as they are in a cool location where the soil will not be allowed to dry out for extended periods. It can be grown in average soil, but prefers an organically rich, moist environment. Under ideal conditions it will spread indefinitely, yet it is easy to control and is non invasive. It blooms late spring to early summer, May and June. Zones 6-7
Propagate by division in early spring or fall.
Though thymeleaf bluets create a dense mat, they are not a good weed suppressant.
