Only a few very small blooms at the beginning of the season, none since. Although it has been a hard summer for bedding they did get good care, and I have had great success with these from Sarah Raven in the past. Disappointing. I am putting it down to the weather however and will try again next year.

Surprised that these did badly. I split them between my garden and my Mum's (50 miles apart), and they didn't flower well at all, even in this baking summer.

Only two thin little plants survived but they were very late arriving and so well behind everything else. Love the flowers with the African basil and some purple sage.

poor quality

These plants arrived completely torched. Have planted them out anyway but they have not survived. We've had really hot weather recently and they have not survived the shipping at all. But cannot believe that they left Sarah Raven in a decent condition because they are so badly decomposed.

Unfortunately, I am disappointed with the condition of these plants. They look as though they have been scorched by wind or sun. Hopefully, given some TLC they will recover.
I have bought many products from Sarah Raven and always been very pleased with my purchases. Shame about this one

Gorgeous colour

I love these. Their flowers are just the right height to be the ‘thriller’ in a pot, planted with red petunias and calibrachoa. A lovely colour and fragrance, and hopefully they will return next year.
