Echeveria elegans is one of the hardiest plants that you can get. They mature at 10-12cm across and rapidly form offsets. Clumps will eventually form and spread as a carpet. Short flower stems appear in summer with small orange flowers.
It's extremely low maintenance. Will thrive outside in full sun to partial shade and requires minimal water.
Perfect for either pots or in the ground.
Pictured here in a 13cm pot, it will be posted bare-rooted.
