Asclepias incarnata

Swamp Milkweed

Swamp milkweed has big heads of rose pink, sweetly scented flowers. It's not unusual to see two or three butterflies on a single flower at the same time. Swamp milkweed grows naturally in wet soil but also grows well in regular garden soil.

Benefits:

• Attracts butterflies and hummingbirds


• Host and nectar plant for monarch butterflies


• Lovely vanilla fragrance


• Thrives in sun in average or moist soil


• Deer resistant
