I'm planning to plant some milkweed this fall to attract pollinators. I have 100 seeds that are ideally suited for my region, here in Colorado. I'll be planting these both in my yard and close to a local creek. I'd love to hear from anyone who has experience with this—any tips or advice would be really appreciated!

When it comes to planting native milkweed for monarchs, just sticking to hardiness zones isn't enough. You really need to ensure that the seeds you're using are native to your area. For example, tropical milkweed can be harmful if not planted in its native range since it attracts parasites and leaves butterflies misled about the climate. I suggest checking out the USDA plant database and Bonap for the specific species you have to better understand their needs.
When planting milkweed, make sure to put the seeds in the ground to a depth about equal to their width—not too deep! Also, just a heads-up: milkweed can be slow to emerge in the spring, so be patient!
I have a large area to plant and remember them thriving near water. The instructions say they prefer well-drained soil, but from my childhood memories, they seem quite happy near water too. Appreciate the advice!
Also keep in mind that narrow leaf milkweed needs light to germinate.
I checked and my seeds are approved for my local area.
