While Crassula barklyi is also known as "Rattlesnake Tail" and "Bandaged Finger" (no joke!), these little compact towers are definitely not dangerous. These are very slow growing, and they send up lots of branches from the base so eventually you get a cluster. They stay pretty short (max 4"), and occasionally produce a flower from the top of the stem. The flowers smell AMAZING you guys. It is monocarpic, so the stem that made the flower does die, but it will leave you with plenty of offsets so you won't lose it from your collection. Originates from Lesotho, Namibia, South Africa, and Swaziland.
