Unfortunately not all of these plants were the ones that I ordered, several turned out to be pink cosmos as opposed to the yellow Xanthos that I ordered. They were all lovely healthy plants however, but just not quite the ones I wanted!

They were unusual and I liked them but they did not do too well probably because they were in a container and the weather was very hot.

The cosmos were good, the nicotiana were mostly good, but one was rather small and didn't do much. One of the sweet peas was the wrong colour, so I had too many of the pink and not many blue.

Reviewed 17th September 2018 by ANN

Very poor growth although put in a sunny spot , well watered and regularly deadheaded and free from slugs. Remained very small and did not thrive as I expected them to. The same plant I bought in a local garden centre performed very much better.

Lovely colour - very unusual and they are keeping going in the border well. Again they have taken a while to get going and are much smaller and weaker plants than the pink ones so it hasn't been possible to pick any because of the short stalks.

They didn't do too well, flowers very small, some misshapen, tall plants but no large beautiful flowers: probably the fierce drought and sun. Better luck next year!

The service was good but over half of the seedlings were suffering with ‘damp off ‘ and did not survive. I complained and some other plants were sent but the quality was not up to the usual standards of Sarah Raven

Lack of water not much help - we only not use grey water and it doesn’t go far. Could have been bigger I expect.

I love cosmos and was delighted to try these new shorter ones, which are a gorgeous colour and are much more manageable being smaller- don't need staking and don't fall over. Prolific and wonderful! I adopted Sarah's idea of putting them in a pot and they look great - a lovely delicate pale lemon colour.
