Like all thymes if they have something to climb up, it will. Filling in the space with dirt, so the thyme may be planted level with the stones, will provide a smoother, flatter look.
Elfin Thyme flowers are the typical lilac color of most thymes. The tiny flowers are held very close to the ground. Some years it blooms a lot and some not so much. It blooms in early summer rather than in spring like many other ground cover thymes.
Elfin Thyme, like most thymes, needs at least five hours of sun a day to keep it from reaching for light and getting leggy.
Elfin Thyme’s small, closely spaced flowers and leaves makes it not only one of the smallest thymes but also one of the slowest growing thymes. Elfin Thyme is a good choice for planting between stepping stones where spaces may be very small.
