and producing numerous deep scarlet flowers.

It is better that they are repotted regularly. Repotting will increase
the number and size of stems and will increase the number of flowers
produced. Repot yearly until reaching about 100mm in size, then every
two or three years will suffice. Repotting is best done at the end of
winter but can be done at other times. Do not water for a couple of
weeks after repotting to reduce risk of root rot via broken roots.
