Plant Details

A magnificent plant with almost dark brown, almost black flowers, scented strongly of chocolate, in mid and late summer. Loves a hot sunny position and needs protection from frost. We grow ours at home in a large pot and move it into an unheated greenhouse over winter.

Introduced from Mexico in 1835. Related to the Dahlia.

Very fragrant. Makes a superb cut flower with long stems.

Height: 60cm

Common name(s): Chocolate Flower, Black Dahlia, Chocolate Cosmos, Black Cosmos.


All our plants are supplied in at least 9x10cm pots. Plants in this size pot establish quickly in the garden and often outpace plants planted in bigger pots at the same time. We do not sell 'plug plants' because those need to be grown on before planting. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow everything we sell ourselves, in our nursery in the Buckinghamshire countryside.
