A staple of seed caalogs of in the 1800s, when it was known as Carnation Poppy, P. laciniatum is now increasingly rare. A classic poppy with deeply cut petals gathered into frilly pompons of bloom. Steel blue foliage sets off the vibrant colors of purple, red, white, pink, and lavender that burst into voluptuous bloom in early summer from a spring sowing. Self-sows.
