Cosmos atrosanguineus 'Spellbound' (Large Plant)

Bidens atrosanguinea, Chocolate Plant

Half-hardy Perennial

A particularly striking Chocolate Cosmos with rich maroon daisy-like flowers and a seductive chocolate fragrance. Cosmos atrosanguineus 'Spellbound' is a choice half-hardy perennial for a sunny border, and well loved by pollinating insects. Plant it among other perennials to support its stems - it associates beautifully with hot fiery colours. Although perennial, the Chocolate plant is often grown as an annual in the UK, but can easily be over-wintered if grown in containers and kept in frost free conditions. Height and Spread: 60cm (24").

Cosmos atrosanguineus is generally grown as an annual but in very mild areas it may be perennial. It can be over-wintered if grown in containers and kept in frost free conditions. Keep the compost barely moist during the winter months. Plants should be watered freely as they come back into growth the following spring, and moved outside after all risk of frost has passed. Alternatively, lift the tubers before first frosts and store in trays of barely moist peat. Keep them somewhere cool but frost-free over winter.
