Anisodontea

No, it doesn't look tough. Very pretty though. Can you bring it indoors B?

No - I'm treating it as an annual. The Nursery I got it from sells them at 'silly' prices, so I don't mind. It flowers all summer, so it's worth it.

Sorry to be a bit late with my comment Spritzh ? but
I got 2 of these last year, the the label said half hardy perenial. As you said they flowered their socks of all summer but both have also survived our very wet windy and exposed winter, not too much frost though... I have pruned them and hope to keep them going for a few more years, seeing our winters are supposed to get milder.

The one I bought last year has survived, which surprised me, Resi! I'm very pleased. :-)))

Mine have both survived this winter, I dug up one and moved it as it outgrew its space and will have to do the same for the other one. So much for tenderness! I've cut them virtually down to groundlevel. The RHS will have to change their advice ?...climate change maybe?
