I've got a flat of 60 that has been outside for the past few freaky warm weeks. Nice to have them hardened off, but they are still a bit small. I still have the one from last year in a pot from which I collected the seed I distributed. It survived fine over the winter without any pest problems and has a carpet of tiny volunteer seedlings in the pot and has started to once again throw out some blooms. I'm pleased that it seems so easy to start from seed. I am looking forward to seeing this year how well a sizable patch of it will attract hummers.
