Growing Orange Milkweed Seeds

Bee introduces how to plant

Plant Milkweed: Sow milkweed seeds ¼ in. deep in 2 in. pots or cell packs. At 65-70°F, germination is within 14-21 days. Transplant seedlings into the garden 12-18 in. apart, well before seedlings become root bound. Can direct sow into prepared seed beds in groups of 3-4 seeds, spaced 1-2 ft. apart. Thin to the strongest plant.

Grow Milkweed: Full sun. Asclepias tuberosa tolerates heat and drought, needs only occasional water once established, will happily accept average moisture with good drainage.
Milkweeds attract bees and hummingbirds, are important nectar sources for a wide range of pollinators and provide essential nourishment for monarch butterfly larva. Plants are deer and rabbit resistant. Pinch seedlings to encourage more flowering stems per plant. Asclepias tuberosa does not have toxic milky sap like other milkweeds.
