Cosmos atrosanguineus Chocamocha

Chocolate Cosmos

Fantastic scented flowers

This plant is chocolate by name and chocolate by nature. The dark purply-brown flowers not only look like rich dark chocolate but they also carry a subtle chocolate scent. Slightly more compact than other forms of cosmos they are easy to grow and look stunning planted amongst white flowering plants or light coloured foliage where they dark blooms create and stunning contrast.


Often grown as a annual it can easily be grown as a perennial if given sheltered conditions over winter.


For best results plant in a container and move indoors over winter.

This deliciously scented Cosmos originates from Mexico

Planting instructions

Choose a container, with drainage holes at least twice the size of the one the plant is currently growing in. Place stones, broken up flowerpots or polystyrene in a thin layer over the holes to help with drainage. Place a layer of multi-purpose compost on top. Remove the pot and position the plant so the top of the rootball sits 2.5cm below the rim of the pot. Fill around the rootball with compost, firming as you go. Water in well and keep well watered especially through dry spells.

Planting site Cottage garden, Informal garden, City garden, Courtyard garden, Flower border and beds
