Curio âMount Everestâ is a true foliage plant. Itâs compact, reaching a maximum height of 40 to 50 centimetres. The plantâs diameter is usually not more than 15 centimetres. So itâs a manageable specimen. The fleshy leaves grow around the stems at a steady pace, so it requires a bit of patience. But donât worry, your wait will be rewarded with a beautiful waxy, smooth branches with a bluey-grey coating.
