Sowing, Seeds, Planting | Sow under cover in mid spring and plant out after last frosts, or direct sow early May. Grow seedlings on in individual pots or modules until large enough to plant out. Gradually acclimatise to outdoor conditions for 7-10 days before transplanting into the garden after all risk of frost has passed. |
Care Tips | Pinch out tips at 15-20cm to encourage bushier plants. Stake and tie Cosmos plants if necessary during the growing season, water regularly and dead-head to prolong the flowering season. |
Flowering | July - 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. |
Harvesting | Flower production 5 months |

Cosmos bipinnatus 'Xanthos' reviews
Reviewed 11th August 2019 by Susie They are good healthy plants and flowering nicely. |
Reviewed 1st August 2019 by Nicky I didn’t realise they would be so small not sure I’d buy them again |
Reviewed 1st August 2019 by Angela Theses never fail and make such good fillers |
Reviewed 1st August 2019 by Madeline Plants in my total order were all healthy and arrived on time and are flowering beautifully. Thrilled. |
Reviewed 31st July 2019 by Angela I think I had better results when I sowed the seeds, rather than taking the seedlings. |
Reviewed 31st July 2019 by Catherine First packet only a small amount took. You had to send another packet which were fine |
Reviewed 31st July 2019 by Jo Hughes I don't like these as much as I thought I would. The colour is lovely, but they have not taken to my garden so are quite small and the flowers are consequently small too. |
Reviewed 31st July 2019 by Jenny Service always good,cosmos disappointing - v small flowers & unhealthy foliage. |
Reviewed 31st July 2019 by Trudy Lost all but one of the plants as they had rotted on the stems, however they were replaced with stronger better quality plants which have thrived. |
Reviewed 31st July 2019 by Bev Such healthy plants when they arrived! and they have grown beautifully |
Reviewed 31st July 2019 by Kath Service excellent as always . Plants arrive well packed and in good condition ready to go . These seedlings were slow to start due to the cold spring but have since thrived and are just the right size in a large tub ....their gentle creamy colour mixing well with other things and still lots of buds to come. |
Reviewed 31st July 2019 by Carolyn Excellent service, but haven’t had one flower on any of the now full grown plants |
Reviewed 31st July 2019 by Melanie A darker yellow and a shorter plant than I imagined but they are nice plants |
Reviewed 31st July 2019 by Maralyn Fantastic in every way. High success rate and a beautiful flower which just keeps on giving |
Reviewed 31st July 2019 by David Everything arrived on time |
Reviewed 31st July 2019 by Marja No luck with these for me. Other varieties did fine though so maybe it was just bad luck! |
Reviewed 31st July 2019 by Lynda Healthy plants delivered quickly. |
Reviewed 22nd November 2018 by Sue Struggled a little bit, think it was very dry summer. |
Reviewed 21st November 2018 by Holly 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! |
Reviewed 21st November 2018 by Philippa Good. Buying and delivery were all absolutely fine. Plants were good. |
Reviewed 17th November 2018 by Jo Peters 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. |
Reviewed 15th November 2018 by Gillian Very pleased with the cosmos seedlings. Very pretty colour. |
Reviewed 14th November 2018 by Jo Peters 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. |
Reviewed 14th November 2018 by Deborah Still in flower this November |
Reviewed 8th November 2018 by Eileen Very simple to order and the plants were excellent. Really good results in challenging conditions |
Reviewed 8th November 2018 by Susan They were beautiful and still producing the odd flower |
Reviewed 7th November 2018 by Anita Again great flowering throughout the summer |
Reviewed 7th November 2018 by Helen Beautiful plants and flowered well through the summer and beyond. Love the delicate yellow. |
Reviewed 7th November 2018 by Madge Cosmos is a very good buy. Excellent for cutting and last well. Will buy again |
Reviewed 7th November 2018 by Yvonne Plants and flowers were on the small size, still pretty though. Quite a dainty plant. |
Reviewed 11th October 2018 by Sue Excellent colour and bushy form |
Reviewed 24th September 2018 by Annie They have been fantastic. I've dead headed a lot and they are still flowering. Beautiful colour. |
Reviewed 21st September 2018 by Alison I bad plant the other four have done very well but I was surprised at their late development perhaps it was the weather |
Reviewed 19th September 2018 by Shirley

Reviewed 19th September 2018 by Gina 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. Reply from the Sarah Raven Team:"Thank you for leaving your review. We are very sorry to hear of your disappointment with your Cosmos and have refunded you for them." Posted 7th November 2018 |
Reviewed 17th September 2018 by Alison 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. |
Reviewed 12th September 2018 by Zara 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! |
Reviewed 12th September 2018 by Jane Lost a few seedlings in the first week. Overall excellent |
Reviewed 6th September 2018 by Helene Please see the comment left for "Cranberry Click". |
Reviewed 4th September 2018 by Gill I grew them last year and Will again next year.they flower their socks off |
Reviewed 4th September 2018 by Anne Stunning plants that have flowered all summer long and still going strong. |
Reviewed 4th September 2018 by Sarah 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 Reply from the Sarah Raven Team:"Thank you for leaving your review. We are very sorry to hear of your disappointment with your cosmos 'Xanthos' and have refunded you for them." Posted 7th November 2018 |
Reviewed 3rd September 2018 by Mrs Jack Lovely bright yellow flowers which show up beautifully in my mixed border. Would recommend . |
Reviewed 3rd September 2018 by Sue
Not as good as the cosmos I purchased from you last year |
Reviewed 3rd September 2018 by Victor

Reviewed 3rd September 2018 by Sally Good strong plants on arrival , but some have done better than others also some are really pretty whilst others are ordinary |
Reviewed 2nd September 2018 by John Needs constant dead heading though pretty colour. Also a bit small for my taste. |
Reviewed 2nd September 2018 by Theresa The salvia was eaten by slugs - not your fault - out of 5 cosmos only 3 bloomed , two died . the thalictrum looks ok but has not flowered which is a disappointment . |
Reviewed 31st August 2018 by Helen These had to be replaced. The replacements were strong and did well |
Reviewed 30th August 2018 by Norman

Reviewed 29th August 2018 by Vivian I planted these out and they are excellent they flower non stop.The service is also very good .if I speak to customer service they are always very helpful. |
Reviewed 29th August 2018 by Mrs Goslett they were rather weak which is surprising as i have had very good ones from you for years Reply from the Sarah Raven Team:"Thank you for leaving your review. We are very sorry to hear that your cosmos 'Xanthos' have failed to perform well this year and have refunded you for them back on to the card that you used when placing the order." Posted 7th November 2018 |
Reviewed 29th August 2018 by Ann Lack of water not much help - we only not use grey water and it doesn’t go far. Could have been bigger I expect. |
Lovely Cosmos
Reviewed 10th August 2018 by jacquie low 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. |
