If, as I think, you are asking if seeds sown in pots or soil, can become too hot, and fail to germinate, the question is definitely yes. The soil should be a bit warm to the touch (and moist). If it is hot to the touch and dry, chances are that the seeds in it are toast. If it is hot and moist seeds are closer to soup (but still probably dead). This can happen very easily in a greenhouse, where pots can heat up astonishingly fast on sunny days.It's true also for hot climate plants, like chillies.
It' s always better to keep seeds in pots in somewhat shady positions.
If you sow directly outside make sure to water gently once or twice a day in very hot weather until seeds germinate (and for a few days after).
If you question was totally diffrent, don't know, I tried
Edd sorry I've had to walk the dogs and sorry for not being clear what I ment. Just sown some pot marigold & cosmos,will they get too hot left in the sun or do I have
Did you sow them into the ground or into pots/containers?
Either should be fine, although most varieties of cosmos grow into giants.. so you'd need a very large container. Full sun should be ideal, but you must keep them well watered until they are growing along well. Thin, then give them deeper less frequent soakings.
Blue onion I've cut empty toilet rolls in half put compost in and down 2 seeds in each then put them in trays covered them with cling film and left them outside I can plant them in the borders when the spring flowers have finished.

I think he means 'sown'.. but auto-correct is getting the better of him.
Between Logan's autocorrect and my "stuck" keyboard missing letters, it's a treat
Pot Marigolds [ Calendula ] and Marigolds [ Tagetes ] are very different plants, the first are hardy and the second are not.
Generally hardy annuals come from all over the world, half hardy plants come from warmer climates.
When you don't even know who's in the team
S.Yorkshire/Derbyshire border
to move them?
