With rich ruby red flowers combining with a deliciously seductive chocolate aroma, Cosmos atrosanguineus 'Spellbound' is a most attractive choice for a sunny border. It is loved by pollinating insects too, so it's a great choice for a wildlife garden. The Chocolate Plant likes to grow in moist, well-drained soil and is best grown among other perennials which will support its stems. It is usually grown as an annual in the UK, but it can be kept over winter if it is grown in a pot and kept in frost free conditions. Height and Spread: 60cm (24).
