Thanks Val I used to have a orange one also, because I was too generous sharing my plants one year I must have given all of it away by mistake
they are very easy to grow from the seeds that form in the pod below those twisted flowers, if I ever see any for sale I will buy more as I never water them when they are in the ground only when they are in pots..
They are pretty Gwen those twisted ones are the flowers after they have finished flowering.
