The plants will need a period of hardening off before you plant them out, whether it is now or in spring. Given they've been inside, I think I'd wait until spring because they will be tender.
Foxgloves are fully hardy outside, however, and even young plants will get through winter in a sheltered spot. They won't flower this year now, I'm afraid.

I'd have said get them out ASAP before the weather turns cold - I find they're as hard as nails. For future reference they didn't need starting off indoors, just sowing the seeds outdoors would have been fine, but not to worry.

If you're not sure you could always put half of the plants out now (plant them out where you want them to grow) and keep half indoors, hardening them off in spring.

Foxgloves are biennials or short lived perennials - they flower in their second year of growth and I find that a few flower again the year after that.

They also seed themselves once you've got them in your garden. :-))

Agree with Beattie - plant immediately, while the weather is so warm, they won't need hardening off at the moment - but by Monday, they may do.

Thanks everyone for advice. Its on a stoned area Spritz so seed wont spread. Thought planting in pots would give them a head start, as the seeds at bottom of plant are still only pin head size. I know stoned is not best but easy maintained as away quite a bit.

That's what you think! They'll be popping up out of cracks and crevices and any soil within 20 feet in a couple of years. They're not problem plants as they're easy to get out, but they are prolific.

When I read that comment from Antz, I had to chuckle, for exactly the same reason. Yes, they will pop up - but you might find they look great where they appear! :-))
