Common Milkweed, Heirloom Seeds — The Essential Monarch Butterfly Host Plant With Beautiful Deep Pink Blooms

Common Milkweed (Asclepias syriaca) is the essential host plant for monarch butterfly caterpillars — and far more than just a “useful” plant. Beautiful bouquets of deep pink to purple blooms make excellent cut flowers. Grows upright 3–4 feet high and 2–2½ feet wide with good branching. Easy to grow and spreads readily — best on the garden’s perimeter or in neglected areas. Perfect for butterfly and meadow gardens. 50+ seeds per packet.

Why Grow Common Milkweed?

  • Essential monarch butterfly host plant — the only food source for monarch caterpillars
  • Beautiful deep pink to purple blooms — excellent cut flowers
  • Easy to grow — spreads readily in open areas
  • Perfect for butterfly and meadow gardens
  • Open-pollinated heirloom — save seed year after year

Growing Notes

Cold-stratify seeds for 30 days before sowing, or direct sow outdoors in fall for natural stratification. Sow seeds ¼ inch deep in full sun. Space plants 18–24 inches apart. Water consistently until established — drought tolerant once established. Spreads by rhizome — best planted on garden perimeter or in wild areas. Monarch caterpillars will feed on foliage — this is a sign of success, not damage.
