I bought one two years ago and, though can be tender, it survived in a pot over winter. It's really lovely and I would like some more. Anyone know where is the best place to get them from?

Can you not get another from the same source? Otherwise if you google, various outlets - nurseries, eBay etc come up in the search results. Many places will post out nowadays.

It was from a local  nursery, but can't remember which one. Did goggle but only a couple supply perennial plants - the rest are annual seeds. Only one did mail order but they were out of stock - naturally I suppose, for this time of year. Just wondered if anyone else has found a good place.

Personally, I'd take great pleasure in touring round them, finding out which one it was.
