Has anyone successfully grown this from seed? I bought a plant today from Morrisons - they've opened their outside garden bit for the first time this year hooray - after hearing so much about it on here 
I've read about taking cuttings but my success rate isn't brilliant. Willing to try though. In the meantime one popped up last year in a mixed pot I inherited. It has quite a few dried seed heads on it that I was about to discard. Is it worth scattering the seeds?
