Marigolds - Seeds

i was dead heading my marigolds the other day and as i was about to put them on the compost heap i noticed the seeds inside one of them. they already looked dry to me so i just put them in an envelope ready for next year.

if you think they need drying you could just lay them on some tissue on a sunny window sill

I do that too
I started off with f1 seeds, so now have a strange mix, some browny orange some bright yellow, some singles and some doubles
But they are all free and keep the whitefly out of the greenhouse
