Thymus serpyllum 'Magic Carpet'

Common Name: Creeping Thyme

This low maintenance lawn alternative forms a low carpet of delicious lemon scented, dark green leaves smothered in pink flowers from early through midsummer. 

It is deer resistant and works well in rock gardens, planted around stepping stones, and at the edge of rock walls.

Though it is listed as being hardy to zone 4, gardeners in colder climates may find it to it be more cold hardy than that.
