Milkweeds have a thick milky sap and a unique flower plan. There are 5 sweptback petals and a 5-parted cup, or crown, with 5 beaks that curve centrally toward the stamens and a pistil. The radially symmetrical flowers are in umbels, often drooping. The paired seedpods are often joined at the base, and the seeds are attached to flossy tufts.
