How did this happen, a flower that smells like chocolate? Combine the scent of chocolate, attractive velvet-soft burgundy coloured petals, neat foliage & drought resistance & you've got the perfect plant. Chocolate Cosmos or to give it it's full name, Cosmos atrosanguineus ' Dark Secret' will make a real feast for the eyes (and nose)in patio containers, mixed borders or as a bedding plant. It's happy with semi shade but loves the warmth of full sun too. Height & Spread: 50cm (19).
