Atlantis is a low, spreading sedum with small, toothed green leaves edged in thick cream, forming a bright mat just a few inches tall. Cool weather washes the variegation with pink. It brings crisp, clean color to hot, dry spots where little else stays this tidy.

Give it full sun and well-drained soil, then leave it alone: drought, heat, rocky ground, deer, and rabbits are all shrugged off. Use it in rock gardens, along curbs and walkways, in troughs, or spilling over container edges. Steer clear of soggy winter soil.
