Special Instructions: Once this plant becomes established, it is difficult to transplant because of its deep taproot. Plant it where it will not be disturbed. Spreads readily through underground rhizomes. Plant in garden where expanding growth is desired, or growth can be controlled, or in containers. Deadheading flower clusters before pods set will prolong flowering period and prevent reseeding.
Harvesting: For longest vase life, cut flowers when 1/2-2/3 of petals are open. Sear the stem end with a flame to prevent the sap from sealing the stem. Wear gloves; milkweed sap can cause skin and eye irritation and can be toxic if ingested. Change vase water often.
