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. |

Cosmos atrosanguineus 'Chocolate' reviews
Reviewed 20th April 2020 by Catherine These did not survive posting, poor little plants, I think too small and immature to sell as ready to plant. |
Reviewed 2nd August 2019 by Edwina two of the plants were poor quality but the remaining three have done well and look good with Geranium Pink Capitatum and Verbena Bampton in a pot on the terrace |
Reviewed 31st July 2019 by Susan Totally mouthwateringly gorgeous. |
Reviewed 31st July 2019 by Frances Great sturdy plants, have started flowering, look very attractive and have placed in a large pot surrounded with other Sarah Raven annuals. Smashing combination, great service as ever. |
Reviewed 31st July 2019 by Lois These are alive but haven’t done as well as the seedlings I bought from another company |

Reviewed 31st July 2019 by Mr Tinsley very satisfactory and have grown well |
Reviewed 31st July 2019 by Lesley All three are flowering and spreading. The cold June held them back but they have improved with the warmth and rain |
Reviewed 31st July 2019 by Andrew Nice plants, well packed, the plants have flowered well in first year |
Reviewed 31st July 2019 by Jane Very pretty, truly chocolatey smelling flowers! |
Reviewed 31st July 2019 by Lynda Healthy plants delivered quickly. |
Reviewed 31st July 2019 by Chris 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 |
Reviewed 21st November 2018 by Mrs Lee 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. |
Reviewed 21st November 2018 by Gavin The plants were delivered on time, in excellent condition, healthy and packaged in a way which meant they were free from damage. I opened the package asap and planted a few days later. Super healthy plants flowers for months. A very satisfied customer!!! |
Reviewed 11th November 2018 by Susi They were fine although the flower heads were rather small |
Reviewed 10th November 2018 by Sally Worth the wait as plants flowered for ages. |
Reviewed 8th November 2018 by Janet 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. |
Reviewed 19th September 2018 by Elizabeth 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. |
Reviewed 19th September 2018 by Wendy Beautiful plants that gave me great pleasure. |

Reviewed 3rd September 2018 by Jayne Not 100% pleased with the flowering. Very poor. Reply from the Sarah Raven Team:"Thank you for leaving your review.

Reviewed 3rd September 2018 by Sandy 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. Reply from the Sarah Raven Team:"Thank you for leaving your review.

poor quality
Reviewed 24th July 2018 by Clare Smith 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.

chocolate cosmos
Reviewed 8th July 2018 by Rose Taylor
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. |
Gorgeous colour
Reviewed 27th June 2018 by Alison Ellis 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. |
