A good companion for Milkweed is anything in the Carrot Family.
Dill, parsley and fennel all are hosts for the Eastern Black Swallowtail, but more importantly, their flowers attract hover flies, whose larvae eat aphids.
Also love Fleabane.

I bought six varieties of milkweed seed last year, put them in the fridge and started then in trays in early April. I just transplanted about 50 plants in the a field next to to my fence. Beautiful!

I have the common and swamp milkweed. I started a butterfly garden and I have so many varieties showing up. I also live in PA. The plants I have are the milkweed as I stated, bee balm, New York ironweed, agastache, butterfly bush, cat mint, denim and lace Russian sage, 3 types of echinacea and Shasta daisies. I have 3 hummingbirds, Monarch, tiger and zebra swallow tails, hummingbird moth and praying mantis. The bumble bees love the agastache blue fortune and the small Russian sage.

People never mention how good they smell. I didn’t even know that they smelled so good until I visited a native plant nursery here in Pa and there was a summer downpour. I loved the earthy smell they gave off!

I’m growing 100 swamp milkweed plants from seed right now to plant in a marsh behind my house. I live in MA. Wish me luck!

I’m in my 20’s and have always loved gardening but I didn’t know the significance of this plant for the Monarchs till now. I’ll be planting this winter to help out. Thanks for the video!

I'm at an Earth Day event in San Antonio and this video convinced me to pick up a swamp milkweed and use it to kick off a rain garden

Came for the common milkweed, subscribed for the swamp milkweed.
I love your channel; lots of good information, no filler.
I found a swamp milkweed plant by the road, and snagged some split pods with lots of seeds (several miles outside of Yosemite National Park). Now I'm moving back to the coast, where I'll plant them in my front yard, along with common milkweed.
Thanks for another good video!

Thank you for sharing the butterfly plant information. I am growing Asclepias Incarnata - Cindrella Milkweed from Monrovia in N. California. This is the second year and the plant is attracting the Monarchs. It is a beautiful sight to see the butterflies coming to this plant. :) I purchased more plants (i.e., Ascelepias Incarnata - Monarch Rose and Asclepias Speciosa - Showy Milkweed) at the Mid City Nursery in Napa, CA yesterday. Also, I am growing Buddleia bushes, Lily of the Nile, Italian parsley, and Jupiter's Beard (i.e., Centranthus Ruber) to feed the other species of butterflies. I have no catepillars; there are yellow eggs on the Cindrella Milkweed. Suggestions are needed/welcomed for more butterfly plant species that will grow in N. California in clay soil/amended soil - Thank You!

I am soooo excited!!! My very first milkweed patch is blooming!! I planted 2-3 scrawny little plants last year and really didn't think much would happen... this year I have about 9-10 big healthy beautiful plants!!!

Really been enjoying these videos. I live in a city but have a big empty field beside my house where the hydro cut is and I’m trying to turn the field into a wildflower meadow. Learning lots from your videos. Thanks keep it up.

Here in Eastern Nebraska, you might have to drive several miles before you see any..The common Milkweed is everywhere. Been seeing more Monarchs everyday now..

[woodridgeretreat]

Great video! My research tells me that Swamp Milkweed does spread through rhizomes, like its cousin, Common Milkweed, though is slower-growing and less aggressive. I have also read that although dividing established plants in late spring can be done, the long taproot does not like to be transplanted, so thanks for all the info on starting the plant from seed. Once established, I can rely on its natural spread, allowing the wind-borne seeds to find their way...thanks, again! :)

This, and Butterfly Weed are my favorite milkweeds! Both are beautiful, and well behaved. <3

[myshow]

Beautiful wildflower garden. I'm growing Swamp milkweed in mine for the first time this coming year

[Andrewtalksalot]

Thank you for the info. I just ordered my first batch of this to add to my butterfly garden. Cheers from the Treasure Coast, FL

[LHMH]

Good information but wished you would have included more details about the care of this plant. Does it need trimming back in late fall or winter like the tropical milkweed. Does it need occasional trimming if I want to keep it compact?

[Attikisses]

I finally identified these mysterious plants give to me today....thank you for your informative video. I can finally relax they are in a great place and growing well.

I grew this for the first time this year and it got HUGE but it was awesome. The pollinators LOVED it.
