I grew some delphiniums, I think they were the same variety from seed & I've still got them in pots maybe 5" square.. I want them to get large enough to stand a chance against slugs/snails.
So I'll be potting them on once more & keeping them until they're big enough next year to go in, I'm guessing late spring.
I think they are fully hardy perennials, once they're not tiny baby plants. I'm hoping so anyway, although I don't know exactly what - temperature they are okay up to.
I'm in the south so was probably going to just put them next to the sheltered wall of the house overwinter, like I do my osteospermums, rather than in the greenhouse, so I don't have to worry about watering them. I'd expect them to just disappear below ground as if they were in the ground.
If there is doubt as to their hardiness I could put them in the greenhouse of course. It's unheated in the winter but would offer some protection.
Have potted up all my little plants and will leave them there until next year, Not sure if i will put them in the greenhouse or tuck them in a corner of the gardenwhere they will be clear from any frost or snow. Still trying to find room in the garden for the lavenders i got last year, think i might have to dig up a bit more of the lawn. Hate mowing the grass anyway.
Its s.urprising how quick they grow so check the size pots they are in. I repotted only 2 weeks ago and they already need bigger pots. Glad something likes the rain
Thanks for all your input guys. I have now potted my plants into bigger pots. I put the pots outside a couple of weeks ago but some of them seem to be dying off a little so I am making room to bring them back indoors. The delphiniums seem to have got leggy and have really thin, weak leaf stems so I am hoping they will toughen up over winter.

HELP, the leaves on mine are going red! They are still in small pots.
