I grow Cosmos Purity, living in Cornwall we get warm but wet weather, last years rain helped the growth and plants like petunias didn't survive but these did. This year I'm growing 3 in each small pot, so there's no root disturbance, then straight into the garden when they are hardened off. I found the orange germination not very good, I've got 100's already in the greenhouse, this year I'll put large groups together
