FAQ
Does Prairie Milkweed need cold stratification?
Yes. Direct sow in fall for natural winter chilling, or refrigerate the seeds for about 30 days in a moist paper towel inside a sealed bag before spring sowing.
Is this tropical milkweed?
No. Prairie Milkweed is Asclepias sullivantii, a North American native species. It is a better choice for native monarch habitat than tropical milkweed in many U.S. gardens.
What site does Prairie Milkweed prefer?
Plant it in full sun with moist, well-drained soil. It tolerates average garden conditions once established, but performs best where young plants do not dry out.
Should I handle milkweed carefully?
Yes. Milkweed sap can irritate sensitive skin. Wash hands after handling plants, and keep sap away from eyes.
