I have normally found that Tromba d'Albenga are a little shy to germinate. So I put 12 in damp paper on a sunny windowsill. I was worried they had got a bit too hot. But no they loved it and all 12 now are sporting a root.
Next problem where do I put 12 rampant plants?
Actually very pleased I was I'll this time last year so did not have any. Winter was not the same without them.
