I was not sure what to expect when I planted them in a large planter. Some had buds and some had nothing happening but they have been amazing and given me lovely flowers all summer in my little patio garden and are even flowering now as autumn approaches. I kept deadheading and the flowers kept coming. My neighbours loved them so much they bought their own. They also attracted loads of bees which is fab.

The seedlings of Cosmos Sonata White have done well and the plants are healthy. Three seedlings are growing in a pot filled in peat free compost and the other two are in regular potting compost. the three in peat free compost are stronger overall and do not need so much watering. I marked Sonata White as good rather than excellent because I tried to grow it from seed (which I prefer) and germination was very poor unlike that of other cosmos seeds bought at the same time and grown in the same conditions

I was very happy with the plants, and all flourished in my garden.
Though fine plants, they were not as big and tall as I expected, but this may have been due to the exceptionally hot, dry summer. I dead-headed them regularly, and kept them flowering for a long time, but maybe because of the weather, the plants did not survive as long into the autumn as I expected..

All 15 cosmos seedlings have produced fine plants but having purchased them all as part of a plan for an 'all-white' border it was disappointing and rather irritating to find when they came to bloom 4 of the 15 proved to be magenta/plum colour. Presumably this was the result of an error in the despatch department.

Otherwise I have been well pleased!

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.
