Meconopsis 'Bobby Masterton' (Blue Poppy) is a short-lived perennial boasting nodding, sky-blue flowers. Their 4 overlapping petals surround a bouquet of contrasting golden stamens and a long, slender style. Blooming in early-mid summer, the splendid blossoms are borne in clusters on erect, leafy stems arising from a rosette of oval leaves suffused with red-purple when young. The blossoms give way to decorative seed capsules, which contain no viable seed. This well-known, sterile clone is thought to be a hybrid between M. grandis subsp. grandis and M. baileyi. Planted in small groups, the delicate flowers of this blue poppy will give a color punch to your shady borders and draw attention.
