Haworthia mirabilis var. badia
Along with lithops, haworthias are one of my favorite succulent plants. They are relatively small, easy to grow, and come in a variety of forms, textures, and colors. Haworthias don't require the high light intensity many succulents need, however, I like the stronger colors that develop under lots of sun. Such is the case with Haworthia mirabilis var. badia.
This particular plant was a gift from a friend that specializes in haworthias. The variety name "badia" means reddish-brown.
