Growing Tips

  • Cold stratification can improve germination for many milkweed seeds.

Seed Storage

Unique Facts About Seeds

  • Asclepias speciosa is commonly called showy milkweed and is native to parts of western and central North America.

  • Showy milkweed is a host plant for monarch butterfly caterpillars.

  • Its fragrant flower clusters can attract a wide range of bees, butterflies, and other pollinating insects.

  • Mature plants can produce elongated seed pods filled with silky-haired seeds that disperse by wind.

Growing Instructions

Planting Season: Sow outdoors in fall or early spring. Spring sowing can follow a period of cold stratification to help improve germination.

Sowing: Prepare a well-drained planting area in full sun. Scatter seeds across the soil surface and gently press them into place.

Depth: Surface sow or cover with no more than approximately one-eighth inch of soil.

Spacing: Thin or transplant seedlings to approximately eighteen to twenty-four inches apart.

Sunlight: Provide full sun for strong growth and flowering.

Soil: Choose well-drained soil with moderate fertility. Showy milkweed can adapt to different soil types when drainage is adequate.

Watering: Keep soil lightly moist during germination and early establishment. Once established, plants can tolerate periods of drier soil.

Germination: Seeds may germinate within approximately fourteen to thirty days under favorable conditions. Cold stratification, temperature, moisture, and light can influence germination.

Transplanting: Direct sowing is preferred because milkweed develops a substantial root system. If started indoors, transplant young seedlings carefully before roots become crowded.

Fertilizing: Generally, little fertilizer is needed in reasonably fertile soil. Avoid excessive feeding.

Care: Keep young plants free from competing weeds and avoid disturbing established roots. Provide adequate spacing and airflow around plants.

Flowering/Maturity: Showy milkweed generally flowers during late spring and summer. After flowering, mature plants may develop seed pods that split open and release wind-dispersed seeds.
