Unfortunately, I received my cosmos late. I had not received them by the date promised and after getting in touch was informed that the delivery had gone astray. So I was sent a new delivery. Consequently, I planted them in my south-facing garden later than I would have liked. I have had healthy foliage but still no flowers. I’m wondering whether they will flower before the frosts !

Reply from the Sarah Raven Team:

"Thank you for your feedback. we are sorry to hear that your replacement seedlings have failed to flower and can only presume that the hot weather we experience has delayed them. We have made a note on your account, please contact our Customer Services team in the spring if you wish to try another set."

This is the first time I have grown Cosmos from seed - these are so easy to grow and stunning to look at. They will not go unnoticed by anyone and of course the beautiful feathery foliage is an added bonus. I am absolutely delighted with them. As I only have heavy clay meadow grass - all of my seeds and plants are grown in pots and they look amazing plus being able to move them around adds to the changing structure.
