Butterfly Weed Care

Besides enjoying the display butterfly weed puts on, you can also use some stems for cut flower arrangements. The seed pods that develop in late summer and fall are very decorative and make a unique addition to flower arrangements.

Plant outdoors after all danger of frost has passed. Select a spot that gets full sun and has well-drained soil. Amend soil with compost if needed but little other preparation is required.

A little known fact is that monarch caterpillars feed only on milkweed species. Other plants can provide nectar for the adult butterflies, but without butterfly weed and other varieties of milkweed, the caterpillars can’t survive.

You can plant it as a border around a vegetable, fruit, or herb garden, and it makes an excellent plant for a native wildflower garden or meadow. Plant it with other perennials that feed pollinators at different times of the year to support them throughout the whole growing season.

Snip off the pod using pruning shears. Slice lengthwise along the edge using a utility knife. Pry open the seed pods. Scoop out the seeds and fluffy matter inside and place it in a bucket.

Transplant the butterfly weed into a permanent bed in spring just after the last frost. If planting butterfly weed in clay soil, dig in 2 to 4 inches of compost to lighten the soil, or consider building raised beds to increase drainage.

Butterfly weed and milkweed seed pods may be harvested and planted to support Monarch butterfly caterpillars. Butterfly weed grows well from seeds, which must be harvested in late summer and either sown immediately in the garden, or started in spring after a lengthy chilling process. The seeds are viable and will germinate with little care, although they must be planted at the appropriate depth to ensure successful sprouting.

Arrange the starter pots on a propagation mat near a source of bright, indirect light such as near a partly shaded south-facing window. Set the temperature on the propagation mat to 86 F during the day. Turn it off at night.
