This is a nice echeveria Mahogany in a six inch pot, with a straight stem and good leaf formation. These can tolerate bright sun through bright shade -- their deep red shade is darker in bright sun and during the winter. The first two photos are of the plant, the 3rd is of my personal plant -- NOT FOR SALE -- these can get up to a foot wide (or wider!) and you can see it's a darker green because it's been under my shade tent.
Sun requirement: Partial sun
Care instructions: use succulent soil, water sparingly.
