Low germination rate

Reviewed 11th July 2018 by Yoshiko Harrop

I like cosmos sonata so I grow them from seeds along with other types of cosmos.
Last year I thought the germination rate was low and bought plug plants later to fill the gaps.
Tried sowing again this year and got only 6 seedlings.
I sowed pink and white cosmos ‘Popsocks’ under the same condition and 80 to 90% of them germinated by then.
In the end both 6 sonata and popsocks have started flowering, around the same height.
The only difference is that sonata flowers are huge!
Wish the germination rate is better, as I prefer sonata.
I have mentioned about sonata seeds to customer service and they have kindly refunded the money.
