Sowing The Seed

Asclepias flower seeds will need to go through a process of stratification for successful germination. Place your seed packet in the fridge for roughly 3 to 6 weeks prior to sowing.

Asclepias seeds are best sown indoors, where the environmental conditions can be maintained for optimal growth. Sow in peat pots, 6 to 8 weeks prior to the last killing frost, at a shallow depth of 1/16” under topsoil. The seeds will require light to germinate, so it is crucial that you do not cover the seeds with much dirt. Transplant or direct sow outdoors when the weather is warm and all danger of frost has passed.

Growing Conditions

Asclepias plants will enjoy an area that receives full sunlight for the majority of the day. They tend to thrive best in rich, well draining soils. It is recommended to mix any hard, compact soil, with a light compost for better drainage. Water the seeds daily to ensure that the soil is kept moist until germination has occurred. Avoid overwatering as this can cause wilting in the roots and plant life.

Germination & Growth

Milkweed seeds will be slow to germinate, taking anywhere from 14 to 28 days to sprout. The plants will reach a mature height of around 30 to 40 inches tall and can be spaced about 12 to 18 inches apart from one another. Once established, they will attract an array of beneficial insects to the garden, such as bumblebees, butterflies, honeybees and hummingbirds. But most importantly, Milkweed will attract the monarch butterfly, because it is considered it’s major food source.
