Hi can anyone tell how to grow these things. I brought some seeds back from
spain about 9 years ago, it has grown steadily to about 4 ft high, 2 years
ago I had 1 flower for the first time and since then nothing at all.
I over winter it in a conservatory and keep it dry, I have tried feeding it
some years and ignoring it others but I must be doing something wring. My
sister who lives about 10 miles away gets hers to flower every year.
Any advice from you experts out there?
