These kalanchoe are the easiest to grow! They require little care and they drop their babies (which grow quickly) usually under the mother plant. You can remove the rooted babies from the soil or from the plant with no fear of them not taking! Each variety will differ slightly in height. In general, if you keep repotting them into larger and larger pots they can reach 3'-4'H. If left in smaller containers and replace the soil annually they won't reach beyond 1'-2'H. Keep the soil dry to the point of hardness (Unless you are encouraging growth) Don't overwater!
