Asclepias fascicularis is a species of milkweed known by the common names narrowleaf milkweed and Mexican whorled milkweed. This plant is common in the Western United States.
It is a flowering perennial sending up many thin, erect stems and bearing distinctive long pointed leaves which are very narrow and often whorled about the stem, giving the plant its common names. It blooms in clusters of lavender or lavender-tinted white flowers which have five reflexed lobes that extend down away from the blossom. The fruits are smooth milkweed pods which split open to spill seeds along with plentiful silky hairs.
Asclepias fascicularis has the potential to become weedy.
Asclepias fascicularis is a specific Monarch butterfly food and habitat plant.
