Sowing, Seeds, Planting Protect plants from frost in a sheltered environment whilst you pot them on ready to go outside, usually around May time. A greenhouse is perfect but a windowsill or conservatory will do fine (16-18°C is ideal), with plenty of sunlight. Gradually acclimatise plants to outdoor conditions for 7-10 days before moving to their final position. If growing in containers incorporate a slow-release fertiliser into the potting mix.
Care Tips Deadhead to encourage flowering. Mulch to protect from frosts or cover with horticultural fleece. In colder parts of the country, lift plants before the first frosts and store somewhere frost-free over the winter.
Flowering June - October
Vase Life Last 7-10 days, no conditioning needed. Pick fresh straight into water, just as the buds are about to bloom, and do not pick in the heat of the day. Deadhead the main blooms that are drooping and going over after about a week. Place out of direct sunlight.

These did not survive posting, poor little plants, I think too small and immature to sell as ready to plant.

Well packaged, strong, healthy plants which grew quickly. All produced lots of flowers with a good chocolate fragrance over a long period. I bought another variety, Choca Mocha, from another supplier but this was not as good; atrosanguineus Chocolate is a much nicer plant.

Beautiful wee plant, am hoping they survive the winter


Can I remind you here about my dahlia "Bishop of Canterbury" It wasn't the same as the catalogue and rather than reimburse me you promised to replace it if you have it again.

Also you haven't included the above or the scabiosa in this list. Unfortunately it died although it was perfect on arrival.

Two of the plants were not in good condition when they arrived due I think to hot weather conditions but I planted all three and watered them well but only one plant survived.

Didn't do so well this year. I think the extra heat we had this summer took it's toll. Only one plant left. the weather didn't suit any of my penstemon this year.

Reviewed 3rd October 2018 by Claire

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.

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.
