A frequent milkweed of wet flatwoods, wet prairies and floodplain forests throughout most of Florida. The range includes the Gulf and Atlantic coastal states from Texas into New Jersey, plus Tennessee.
A tall perennial with smooth, slender, unbranched stems to 1 m (~3 ft.) tall. The few linear or narrowly lanceolate leaves are opposite, 3-13 mm (1/8-1/2 in.) wide and 10-20 cm (4-8 in.) long. The red to reddish-orange or reddish-purple flowers are in terminal umbels and have five reflexed lobes, five petals and five stamens. Blooming season is mostly spring through fall, but can be all year in south Florida.
Similar species are A. tuberosa - butterfly weed - which has alternate leaves, and the non-native A. curassavica - scarlet milkweed - which has leaves wider than 1 cm (3/8 in.).
Asclepias lanceolata is a member of the Apocynaceae - Dogbane family.
