I have been moving mine in at night and back outside during the sunshine. But I left it outside by mistake tonight, and I hope it's ok. It's chilly out there. Maybe not that bad though, the weather website says it's 12C outside right now. It should be ok. But I wonder what happens if they aren't exposed to freezing temperatures, and you keep watering them --- do they just constantly bloom? This is actually the first tropical plant I've really paid much attention to, all the others I've started from seeds and were annuals. Oh well, we'll see I guess. I'm looking forward to the scent!
