Poor germination

I don't usually have problems growing cosmos but both sowings of this cosmos had poor germination this year (compared to my favourite Antiquity). Maybe I was just unlucky. Really disappointed as it looks beautiful and a dwarf white cosmos really appealed.

Only 3 out of 20 seeds germinated at my first attempt and none out of twenty on the second. None of the 3 surviving plants has yet flowered. This is very unusual for Sarah Raven seeds which I have had no problems with before.

Very disappointed with these, not a single seed germinated from two separate sowings, suspect old seed.

Excellent germination and growing on to be beautiful flowers and foliage for cutting and creating bulk in a border. Highly recommend.
