Growing butterfly weed?
Butterfly Weed
Q. Can I grow butterfly weed from seed? How?
A. Butterfly weed (Asclepias tuberosa) is easy to grow from seed. For the quickest flowers, start seed in late August. Fresh seed requires a period of cool, damp stratification. Provide this by placing the seed in a bag of moist peat moss and keeping it in the refrigerator for ten to twelve weeks. Older seed will not require this cold period to break its dormancy. Direct seed butterfly weed outside, or grow the seedlings in a nursery bed until the plants have five or six leaves, at which time it should be moved to its permanent location. Give the seed proper attention while it is germinating; though the mature plants will tolerate somewhat dry soils, the seedlings need to be kept moist until established. Fall-grown plants will provide moderate bloom the following year, with improved bloom in successive seasons.
If you prefer, you can start butterfly weed in the spring. Follow the same procedures as for fall sowing. Butterfly weed requires winter cold to bloom, so spring-sown plants will not bloom their first summer. However, the long summer days will allow the seedlings to grow into large plants which will produce many blooms the following year.
