This cosmos isnt your average daisy-shaped cosmos. This little beauty is more akin to a pink rose, with its double flower of powder-pink petals; it forms a rather impressive plant that is literally covered in blooms. Keep picking for continuous displays of pink perfection all summer long. This flower was one of the ones that helped me win in the final; perfect feathery foliage and a beautiful bud really impressed the judges. Height 60-90cm (24-36). HHA - Half-hardy annual.Rob's Thrillers - Thrillers are the star of the show, the flower you want to show off and be your centrepiece. One or two of each Thriller, Filler and Spiller can turn a good bunch of flowers into a great arrangement.
