Sun. A cool-season annual blooming in March. The blue leaves spring up like wildflowers during December and January, growing swiftly to 3′ in spring. The leaves resemble dandelion, but without spiny thistles. Nodding flower buds pop upright just before blooming in spectacular scarlet and purple colors, usually around the end of March.
Poppies reseed freely, especially after a wet winter. They can spread out of control in an irrigated setting and even among native wildflowers.
