Chocolate cosmos is absolutely gorgeous and a must-have in the perennial border. It forms a sturdy clump and tall brownish stems are topped with dark burdundy-chocolate flowers which smell just like rich dark chocolate from mid-summer onwards. Very beautiful in a vase with other summer flowers. Thriving in full sun in soil that doesn't dry out too much in summer. Winter dormant but is frost tender so the crown needs some winter protection - a perfect container specimen too as long as it's watered regularly. 60x60cm approximately.
