Shirley Poppy ‘Supreme’
Papaver rhoeas
Description
This mesmerizing mix of white, scarlet, soft pink, and watermelon-orange look like an old-fashioned silk kimono. Single and double flowers sway above clean, mint-green serrated foliage. Each fuzzy stem shoots up at least a half dozen buds, and as soon as one flower fades, another comes up, resulting in flowers all summer long. Blooms have a delicate and ephemeral quality and are well loved by pollinators.

Seed Sowing & Growing Notes
Shirley poppies resent transplanting. Direct-sow into the garden after all danger of frost has passed. Seed can be started indoors, just take care when transplanting out not to disturb the roots too much.
Harvesting/Vase Life
Individual flowers are short-lived, lasting 3 to 4 days if stem ends are seared for 7 to 10 seconds in boiling water. Seedpods can be dried and used indefinitely.
