Creeping thyme ‘Snowthyme’ (Thymus serpyllum) offers white blooms and is ideal for an ecological lawn, it requires little water, grows in poor and dry soil, delighting the eyes of passers-by as the flower carpet unfolds under the noses of pollinators. No need for a lawnmower, except perhaps a simple pass if you prefer to remove the flower stems drying after the long flowering. The aromatic leaves and flowers are intensely lemony and can be harvested from spring to autumn.
