Milkweed Seeds

Originating from diverse habitats across North America, milkweed seeds are adaptable to different climates. They thrive in USDA hardiness zones 3 to 9. Milkweed plants bloom from early to late summer, displaying lively colors of oranges and pinks to subtle whites and greens. Depending on the region and species, milkweeds can grow as perennials. They provide a sustainable habitat for wildlife, adding beauty to landscapes. You can find Survival Garden milkweed seeds for sale here and a variety of other seeds we offer on the main page.

Growing Milkweed Seeds in Your Garden

  • Exclusive food source and host plant for Monarch caterpillars
  • Usually grown as perennials
  • 3 milkweed varieties to choose from
  • Most seeds germinate within 10-15 days


For optimal growth, milkweed seeds should be sown directly into the garden. Fall or early spring is recommended, avoiding the frost. In zones 3 through 7, fall planting is ideal, allowing for natural cold stratification. For zones 8 and 9, spring planting is advised.

Milkweed seeds benefit from being planted in their final location. They develop deep root systems early on and don’t do well with transplanting. The seeds require sunlight to germinate. Simply scattering them on the soil surface will do. Germination typically occurs within 10 to 15 days. Thin seedlings to give each plant ample space to grow. Spacing between plants should be about 12 inches.


Milkweed prefers full sunlight but can tolerate partial shade. At least four hours of direct sunlight daily is necessary. Most milkweed species, including Butterfly Weed and Common Milkweed, thrive in well-drained, moderately fertile soils.

Milkweed, with its lush foliage and clusters of flowers, adds a wild beauty factor to a garden setting. The plant also serves as a crucial food source and nursery plant for monarch butterfly caterpillars, as well as a nectar source for adult butterflies. To encourage a longer blooming period, remove spent flowers, which promotes new growth. After blooming is finished, allow some seed pods to mature. You can save the seeds following the instructions on the back of the packet, or allow the plants to naturally reseed by releasing milkweed seeds for monarchs. Depending on the species, these plants can reach two to five feet. Milkweed supports biodiversity in your local ecosystem and preserves our planet's delicate balance.
