Echeveria Purpusorum. Sometimes known as Urbina, is a super slow growing #echeveria, it will take years to grow to its full size. Check out those reddish-green marbled leaves though, we're happy to wait for it. The leaves are unusually short for an Echeveria.
Pothole Gardening! What a fabulous idea! Walt and I once did a guerrilla cottage garden for a friend who lived in a teeny tiny cottage with a teeny tiny yard. She came home from work one day, and had no idea how her yard had suddenly turned into a blooming oasis. Great fun!
