Its seed pods will turn brown towards the end of the growing season (early autumn) and if left on the plant, they will burst and spread seeds throughout your garden to emerge as new volunteer plants the following spring. While the plant can take up to three years to fully mature and produce flowers, its blooms will gradually grow denser with each season that passes.


Overwintering butterfly weed is a simple matter of cutting off the plant stem near ground level as soon as the plant succumbs to cold temperatures in the fall or early winter. There is no harm to leaving the plant stalks in place, though this encourages rampant self-seeding, which is usually not desired. Don't mulch over the root crowns, as this can encourage rot.

How to Grow Butterfly Weed From Seed

Butterfly weed thrives in a variety of different temperature and humidity settings, growing well in zones 3 to 9.
