Intense, fiery orange flowers top the upright stems of this vibrant hardy perennial. The flowers persist throughout summer, followed by intriguing, spiny seedpods in autumn which split open to reveal silky threads. Commonly known as Swamp milkweed, it is at its best in damp soils, but surprisingly resistant to the occasional dry spell. Asclepias tuberosa is ideal for sunny borders, especially wildlife gardens, where butterflies crowd to its nectar rich blooms. This showy perennial also makes and excellent cut flower.

1 Bare Root Plant (KB1784)

Grow Asclepias plants in sunny borders in fertile, well drained soil. Once established common milkweed is reasonably drought tolerant and will survive dry conditions well. Caution: Contact with the milky sap may irritate skin.
Feed and water regularly throughout the growing season until milkweed plants are fully established. Once established they require little maintenance. Deadhead the first flush of blooms when they fade to promote a second flush of Asclepias flowers. Leave the faded flower heads of any subsequent blooms intact at the end of summer to enjoy an attractive autumn seed head display. When the first frosts blacken the stems, cut them down to ground level. Lift and divide overcrowded clumps of Asclepias in spring.
