Milkweed Orange

Asclepias tuberosa

Milkweed Orange (Asclepias tuberosa), commonly known as Butterfly Weed, is a hardy perennial prized for its bright orange clusters of flowers. Growing up to 2-3 feet tall, it thrives in full sun and well-draining, sandy soil. Blooming from summer to early fall, this plant is a magnet for pollinators, particularly monarch butterflies, as it serves as a vital host plant for their caterpillars. Its drought tolerance and vibrant blooms make it an excellent addition to wildflower gardens and borders.

How to Germinate Milkweed Orange

How to Germinate Milkweed Orange (Asclepias tuberosa)

  • Sow Milkweed Orange seeds directly outdoors in late fall or early spring, as they require a period of cold stratification to germinate.
  • If starting indoors, stratify the seeds by placing them in a moist medium in the refrigerator for 30 days before planting.
  • After stratification, plant seeds 1/4 inch deep in well-draining soil.
  • Maintain a soil temperature of 65-75°F (18-24°C) for optimal germination, which typically takes 14-28 days.
  • Keep the soil lightly moist during the germination period but avoid overwatering, as Milkweed prefers dry conditions.
  • Once seedlings are a few inches tall, transplant them to their permanent location, spacing them 12-18 inches apart.

Additional Tips

  • Milkweed Orange thrives in full sun and prefers sandy, well-draining soil. It is drought-tolerant once established.
  • Water young plants regularly until they are established; mature plants need minimal watering.
  • Avoid over-fertilizing, as Milkweed grows best in low-nutrient soils.
  • Apply mulch around the base of the plants to retain moisture and suppress weed growth.
  • Milkweed is a host plant for monarch butterflies, attracting pollinators and beneficial insects to your garden.
