As a perennial succulent, the black rose won’t demand a whole lot of your green thumb to reach its full height of up to 4 feet and its spread of about 2 feet. Think of your black rose succulent a bit like a little cactus – this Crassulaceae, a native of the Canary Islands, thrives in full sunshine and can deal with partial shade, enjoying about 6 hours of sunlight per day. Even though it’s a little thirstier than some succulents, the black rose is still a plant with low water needs and will only sip a maximum of about 2 inches of irrigation.
