- Description
-
Red Milkweed is a native herbaceous perennial wildflower found in the sandhills, swampy areas, and wet pine savannas from New Jersey south to Florida and west to Teas. It is found in the sandhills of North Carolina.
The plant will grow 2 to 3 feet tall in full sun to partial shade in consistently moist to wet acidic soil. Propagation is by seeds. To save seed, be sure to collect the pod before it splits, as the seeds can blow away.
The pink to light purple clusters of star-shaped flowers appear atop stems in June and July, attracting many pollinators. The plant is a host for the monarch butterfly larvae. Flowers are followed by seed pods that split open to reveal seeds with silky white hairs that are carried by the wind. The stem oozes a milky latex sap that some my have an allergy to so where gloves to handle.
Use this plant in bog gardens or other moist to wet sites as along a stream or pond or in rain gardens.
Insects, Diseases, and Other Plant Problems: No significant disease problems. Most common milkweed pests (aphids, milkweed beetles, Monarch larvae, and milkweed tussock moth larvae) are not problematic, but both large and small milkweed bugs can be very damaging to seed pods.
