Make a positive impact on your garden and local ecosystem by buying swamp milkweed seeds and planting them for pollinators!

Hummingbirds, bees, butterflies – all pollinators love milkweed blooms. Their blooms last a good month in the heart of the summer, providing a long-lived nutrition source for our pollinator friends.

I achieved nearly 100% germination with these seeds early spring, 2023. They are ridiculously easy to grow. They need zero maintenance during the summer, but would certainly appreciate some balanced fertilizer once a year. I’ve also had zero pests or fungal problems with these milkweeds for the 4+ years they’ve been in my garden. The images shown are the mother plants all these seeds come from.

Here’s why you should consider growing them:

You can grow these beauties in two ways:
1. To get a jump start on having milkweeds growing strong in your garden next year, place these seeds in an airtight container (NOT the paper packets they come in!) in the refrigerator for at least 30 days. This simulates ‘winter’ and will prepare the seeds for growing soon in the spring.
2. These seeds can also be directly sown in your garden in the fall, to have them growing as soon as Spring returns!
