The flowers fade quite quickly, so it is important to encourage more buds to form. To do this it is really worthwhile to dead head the old flowers. This can be quite tricky as the buds and the immature seed heads look pretty much the same! The easiest way not to pull off the buds by mistake is to remember that the plant flowers advance down the stem. So a bud will be ahead (nearest the growing tip) of the open flowers and the developing seed heads will be behind (nearer the plant). Nip the developing seed heads off with your finger and thumb and this will make the plant make more buds and flowers.
