Germination rate 1 in 48

by

I have been trying to start these indoors for a month now. After waiting 2 weeks for the first seeds to germinate and getting zero, I reseeded. It's been another two weeks, so far I have a grand total of one tiny plant. Very disappointing. The other variety of cosmos I seeded four weeks ago is almost ready for transplant. This variety is just not growing at all. Both varieties planted under identical conditions.

They were very beautiful

I absolutely loved these flowers they lasted the whole season I’m not sure why someone would give it a bad review. They were very beautiful
