Cosmos atrosanguineus 'Black Magic'
Always desirable, always expensive, Chocolate Cosmos is one of those plants we've not propagated to date as it could only be grown from tissue culture or unreliable vegetative means. That's changed.
'Black Magic' was developed in Germany from one single seed-head received from a private garden in New Zealand. The seed, although still scarce, is now available to the smaller nursery. Originating in Central America C. atrosanguineus is a tender perennial so the tuber must be lifted and overwintered in barely moist peat.
Start into growth indoors in mid to late spring before planting out after the last frost.
'Black Magic' has natural variations in both colour and flower form. The leaves can be narrow or broad whilst the flowers are chocolatey or a little redder. The fragrance can be rich chocolate or with a hint of vanilla. Whichever form it takes, it is still a beautiful plant to own.
