Purple Milkweed looks similar to Rose Milkweed (Asclepias incarnata) but the flower color is a rich red-purple color compared to the softer pink of Rose or Red Milkweed. It is also a smaller plant and is not seen growing in fully saturated soils as the Rose Milkweed. There are usually one to three blooms that form near the ends of the stems in late spring, early summer.

The flower is held above the leaves on stems a bit longer then Common Milkweed’s and the umbel itself is stiff, and holds a nicely rounded form, while that of the Common will flop a bit. Blooms can last for about a month and if seed is not set it will occasionally re-bloom. The average height is around 3 feet, but it will sometimes go to 4 feet. The flowers will attract a variety of nectar-seeking insects and is a larva host Monarch caterpillars. The leaves are big, around 6-8 inches and they taper to a point at both ends. The mid-vein in the leaves is tinted with the same color as the flower.

Grow Asclepias purpurascens in a site that is well drained but has ample moisture. It seems to prefer a bit of shade but will do well in full sun if it gets deep, regular watering. This Milkweed will not spread aggressively like the Common does.
