Good, healthy plants that have grown well in a difficult spot in the garden (where they are in competition with some more established perennials and a tree). Would certainly buy again.

Customer service excellent, as always. These Cosmos were to replace some of the original cosmos from the original white collection, which weren’t up to your usual high standard.

These were sent to me free of charge because I had such a poor germination rate with the seeds (unlike other cosmos seeds that I bought at the same time).
The seedlings have grown well in their pot and the plants are very healthy. It is a great height for containers.

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!

They performed ok. The usual pests affected the flowering but that is inevitable. I used slug deterrent on the soil.

Lovely bushy plants, loads of flowers however I wouldn’t grow this dwarf variety again because I think the flowers too big for the over all size of the plant. Next year I’ll try the regular plant.

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.
