Availability: In Stock
Butterflies and hummingbirds will flock to your garden to feast on the sweet nectar of this easy-to-grow, heirloom perennial. Often called swamp milkweed, this species grows best in moist or wet soils, such as near a pond or stream, but the loosely-clumped plants also grow well in a garden with regular watering. Decorative seed pods are beautiful in dried arrangements. Sap is toxic; avoid eye/skin contact and do not ingest.

We cannot ship this variety to Hawaii as per state regulations. Please do not order if your shipping address is in these states.

A treat for the butterflies!

5 out of 5 stars Jul 19, 2020
Easy and quick to grow if you follow the directions. For stratification, I wrapped the seeds in a moist paper towel, sealed in a plastic bag, in the fridge for 2-3 weeks. Had 100% germination success rate. Plants grew quickly, even through a few periods of neglect. And the butterflies love them! If you want to help save the monarch butterfly population, grow milkweed in your garden.

Did not germinate at all. Disappointed. I am not a beginner gardener.
Karen Wagner from WI
Owner Response: Hi Karen, We are sorry these didn't germinate for you. Stratification (a cold, moist period) does help tremendously with the germination of this milkweed. You can find instructions on how to stratify on the seed packet. Alternatively, it can be sown in fall and stratify naturally. We do guarantee our seeds and they are tested frequently by a third-party laboratory to ensure germination exceeds both federal and our own standards. A customer agent will contact you soon to help.

I had such a nice growth of this Milkweed in my side yard this year. I should have stratified in the fridge for a higher germination rate, but I was a novice Milkweed gardener and chose to sow the seeds in early Spring. I already have more seeds from Botanical interest to sow this fall and some to germinate in the fridge, because my plants are covered in Monarch caterpillars and I am so excited! The plants didn't flower this year, but I've heard that's normal and maybe because the side yard isn't quite enough sun. I'm so happy seeing Monarchs in my flower patches and their caterpillars eating this Milkweed. I have even sent seeds to friends to get more people growing Milkweed to help the Monarchs.

Owner Response: Hi Jenna, How exciting. Just a tip--you stratify the seeds in the refrigerator (cold and moist) and they germinate outside of the refrigerator. You can also sow the seeds in fall or winter and let nature stratify the seeds for you. You can find more details on the inside of the seed packet or in the Milkweed: Sow and Grow article which is also linked in this product page under "Learn More".

Not Variety Listed on Packet

There were two varieties of seeds in the packet we purchased, Butterfly Weed & Mexican Milkweed. The packet didn't contain any Swamp Milkweed which is what we wanted. Germination rate was great, just not the variety we wanted.

I bought this packet at sprouts because I saw a butterfly on it. As simple as that. I bought the little pods to stick one seed in and I put 8 pods to germinate inside for two weeks. 7 plants popped up. I gave a was two and two and kept three. I was waiting to find homes for them because they grow up to 6 ft. So I figured by the time they were older to be plotted out I would have found homes. But three days ago butterflies started coming around they're about 10 inches tall very hearty. They got infested with red aphids but I washed them off and were fine. Then I notice the butterflies targeting it apart from the other plants. And then I saw it put its bottom on the bottom of a leaf. So now I am excited for this years gardening journey with butterflies. I have found a full sun area to plant them in for their homes. The people who received my other milkweed are excited as well. We went to a local butterfly garden to buy extra milkweed.
