Buy Thymus polytrichus A. Kern. ex Borbás subsp. britannicus (Ronniger) Kerguélen.) Thymus pseudolanuginosus

creeping thyme - wooly thyme

Position: full sun
Soil: well-drained neutral to alkaline soil
Rate of growth: average to fast
Flowering period: June to July
Hardiness: fully hardy

Tiny, pale pink flowers appear in summer amongst small, grey, woolly foliage. This is one of the woolliest thymes available and as its low growing is ideal as an unusual ground cover. Unfortunately it's not suitable as a culinary thyme, but the flowers are highly attractive to bees and other beneficial pollinating insects.
Garden care: Susceptible to root rot in poorly drained soils. If necessary, lightly trim to remove dead flowers, and cut back harder after flowering to keep them compact and bushy.
