The Milkweed Lands Collection

This ecology, captured in our 2023 book, The Milkweed Lands, has edged towards disappearance in our collective lifetimes. In 2012, researchers calculated that some regions of North America have witnessed an almost 60% decline in milkweed abundance since the 1990s.

But the milkweed lands can be restored to their past glory. Sometimes reputed to be “hard to grow,” most people can actually grow milkweeds from seed with some dedication and diligence. While not always producing perfect results, the following general recipe has consistently worked best for us:

1. Cold treat the seeds in a refrigerator mixed with barely damp sand for 30-60 days, checking occasionally to ensure no mold is growing. If it is, wash it off immediately.
2. Soak the seeds in hot tap water for 8-hours after removing them from the fridge.
3. Wrap the seeds in a damp paper towel, place this inside a plastic bag, and leave the package somewhere warm but out of sunlight – such as the kitchen counter.
4. Unwrap and check the seeds daily.
5. Any germinating seeds should be placed into a container with a mix of 50:50 seed-starting mix and sand, and kept in a warm outdoor location out of direct sunlight.
6. Water and care for the young plants daily until they are large enough (6-8 inches) to be transplanted into the ground.

Results can vary, and as we improve our own process, we’ll continue to share those details here.
