Echeveria 'Black Prince'
Echeveria Black Prince features a dramatic deep reddish-purple to almost black color. They love the sun and their color will deepen the more they are exposed. Perhaps only outdone in color by Sinocrassula yunnanensis, it also has very dark red flowers in late fall to winter.
If you like bright colors or deep colors, this is an excellent contrasting pick that will only further highlight your favorites.
