Don't think you'll need the propagator for the seeds you've mentioned - you can sow the foxgloves as soon as you like. Meconopsis should be sown in early spring, but my book doesn't say whether that should be under glass or not, I imagine it should be. As for Agapanthus seed, under glass in early spring, grown on in pots and planted out when good enough in size. Won't flower for 3 years.

Thanks for quick reply Bamboo, i have sown the foxglove seeds so fingers crossed.

I've got some agapathus seedlings growing in my utility room (by the window for warmth - should the sun ever shine again in Cumbria) they're fattening out a little but they're still only 2 to 3 inch tall... when should i pot on and should i wait till next year to plant out? Thanks...

Pot on when they need it, which is when the roots are showing at the base of the pot. If they're a hardy variety, and big enough by the end of this season, then you can plant out in autumn, but only if they're a good size by then. If not, somewhere the compost in the pots won't freeze over winter...
