Swamp milkweed (Asclepias incarnata)


Easily grown in medium to wet soils in full sun. Surprisingly tolerant of average well-drained soils in cultivation even though the species is native to swamps and wet meadows. Plants have deep taproots and are best left undisturbed once established. Foliage is slow to emerge in spring. Plants have a cluster of fleshy roots radiating outwards and are best left undisturbed once established.
