Cerastium tomentosum
Best groundcover for gardeners seeking low-maintenance, sun-loving border texture.
This vigorous perennial is the ultimate low-maintenance groundcover for sunny, rocky spots, creating a striking, silvery mat that erupts in a sea of white blooms. It spreads aggressively to fill empty spaces quickly, though you will need to shear it back after flowering to keep the foliage looking sharp and tidy.
