The zinnias were beautiful, and the last ones are still bringing colour to the garden. I have been very pleased overall with my purchases this year, and have recommended Sarah Raven to friends. My only real problem this year was with the dahlia collection I bought. These were considerably delayed in the post, and perhaps because of that only one flowered; that one was lovely. The "white collection" were planted in a pot by the front door; the cosmos are still flourishing , but the other, smaller, plants did not do as well.

Everything arrived beautifully packaged and in good condition. The plants themselves have been a joy with nothing failing. I have been singing your praises to all my friends!

Service excellent..Some plants failed but on the whole good.
Weather didn't help..again.
Dwarf varieties would have been better.
