Easy-to-grow from Snow in Summer ground cover seeds, this perennial is a great herbaceous ground cover plant which is low-growing, creeping, very dense and mat-like, and 6 - 10 inches tall by 12 - 24 inches wide. Although it tolerates no foot traffic, Snow in Summer performs well as a general flowering ground cover plant.
The very tiny Irish Moss seeds create a moss-like, emerald-green foliage that forms a compact 1 - 2 inch tall carpet. Sagina Subulata ground cover is excellent for planting between flagstones. Grown as a lawn substitute, it creates the effect of a moss-covered meadow. Irish Moss is very soft to walk on barefoot, and it has a slightly spongy feel to it.
HOT and DRY. Drought tolerant Ice Plant (Delosperma) is right at home along this cement curbside. Few sun perennials can take such less-than-forgiving locations yet still provide months of bloom all summer long.
