Buy Cosmos atrosanguineus Chocamocha ('Thomocha') (PBR) chocolate cosmos: Smells deliciously chocolatey

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

    • Position: full sun
    • Soil: moderately fertile, moist, well-drained soil
    • Rate of growth: average
    • Flowering period: June to September
    • Hardiness: half hardy

      A beautiful perennial, with sumptuous, velvety, bronze flowers produced above lance-shaped, blue-green foliage from June to September. The aroma of this new variety is even more chocolatey than Cosmos atrosanguineus and it's more compact too, so may not need staking. Great for growing in a sunny border and looks lovely when planted with other hot colours. To minimise frost damage, protect the tuberous roots with a cloche or overwinter in a frost-free environment.

    • Garden care: In autumn after the foliage has died back reduce the stems to within 5cm (2in) of the roots. Lay in a tray of soil or compost and over-winter in a frost-free environment until early spring.

Notes on Cosmos atrosanguineus Chocamocha ('Thomocha') (PBR)

"For chocaholics, a more-compact form with redder flowers and silver-green foliage - and a stronger chocolate fragrance !"

Chocolate wonder


A garden favourite but rarely survives winter in the north-west. Happy to re-purchase annually. Crocus plants always in great condition. Grandchildren love the chocolate smell.

Nice plant but not compact


I do love chocolate cosmos, however it say's in the description that this cultivar is meant to be compact however the oneI received was very tall and needs stakes to support. We have used this cultivar at my workplace before and it was compact so I suspect I was sent the regular chocolate cosmos instead of the variety I ordered. I still do like it, however was not what I was expecting so slighty disappointed.




Velvety Chocolate Beauty


A beautiful plant with a wonderful cocoa-scented, dark-chocolate flower. The delivered plants were tiny however, and took a while to establish themselves. I have over-wintered them in my cool greenhouse and they are coming through again this year, so worth buying




Stunningly beautiful!


Delicately beautiful, ethereal quality.

I purchased one of these from you last year. Popped it in a greenhouse over winter and have brought it back out. There still isn't any sign of growth. Do you think that there is still time? or have I lost it?

Col Green

Hello, I would have thought that by early June it would have started growing by now if it was still alive, so I suspect it may have died over winter. I would however give it another couple of weeks before you finally give up on it.


I have just received these plants from you, but as this Spring has been so cold, would you advise me to wait until it warms up (if ever)before planting them?


Hello, These plants do need protection from the frosts, so ideally they can be potted up and grown on under glass until the weather improves and they can be planted out - usually from mid-May onwards.


Over wintering Chocolate Cosmos Hello, I wonder if you can advise me on over wintering my Chocolate Cosmos...last year I left three in the ground but only one survived. I don't seem to have any success leaving them in pots, and have tried leaving them in the garage and the shed but they seem to dry out. I have another three to over winter this year, and do not want to lose them again. Your advice would be very much appreciated Many thanks Shirley

Hello Shirley, All plants need light and water if they are to survive, so leaving them in a shed is not ideal. The chocolate cosmos are not hardy, so will need protection from the cold. You need to find a spot that is sunny and bright, but protected from the worst of the winter, and where you can get to them to water. A greenhouse or conservatory is ideal. Alternatively you could leave them in pots and cover them with fleece and hope it doesn't get too cold. They won't however be happy indoors as the central heating and low light levels will not agree with them. I hope this helps. Helen Plant Doctor

How to overwinter tender perennials

Tender perennials, such as pelargoniums, fuchsias, osteospermums and marguerites look great all summer, but unless they are given protection from the harsh winter weather, they will need to be replaced each spring. If you can do this, they will last for y
