Fewflower milkweed(Asclepias lanceolata) is a delicate perennial wildflower found in swamps and moist to wet pinelands and prairies throughout Florida. Its stunning orange to red flowers typically bloom late spring through fall.

Flowers are born in terminal umbels. Each flower bears a five-lobed calyx and five-lobed corolla. Corolla lobes are reflexed. Often mistaken for petals are five hoods (or petaloid appendages) that form an upright corona — a characteristic typical of milkweed flowers. Leaves are long (4–8 inches), linear to lanceolate, with short petioles. They are oppositely arranged. Stems are slender and smooth. Seeds are born in erect follicles that dry and split open as the fruit matures. Each seed is attached to a white silky pappus that catches the wind and aids in dispersal.

The genus Asclepias is named for Asclepius, the Greek god of healing. The species epithet longifolia literally translates to “long leaf,” hence the common name.

Like all members of the Asclepias genus, Longleaf milkweed is a larval host plant for Monarch and Queen butterflies. The plant contains a milky latex that is toxic to most animals, but Monarch and Queen caterpillars are adapted to feed on them despite the chemical defense. The flowers are an important nectar source for bees and wasps.
