Bolivia Crinum Lily has dense foliage made up of strap-shaped leaves from which large white and red, bell-shaped flowers emerge in spring. You can buy one, two or three large tubers with this order. They look a bit like a very big trimmed leek, but are about the size of a small log and it needs to be planted upright in the ground. Just dig a hole about forty centimetres deep and place the tuber in with the rootlets downward then cover with soil, firm down and water well.
