Cosmos
Cosmos is the flower of the modern garden-to-vase movement — delicate, airy, and hyper-seasonal. Chocolate cosmos (C. atrosanguineus) is the specialty version, with a deep burgundy-brown colour and a genuine chocolate scent. Fragile in every dimension; a day-of-event flower, not a shipping flower.
