They're in starter cells on the step outside my potting shed, which is inside of the fence around my victory garden. My plan is to move them to bigger pots after they've had some time to make roots, then transplant them onto the pond dam later in the fall.
Look very healthy! But this must be a strain of milkweed that is unique to your area or maybe this strain is different than northern strain milkweed? Yours looks like it has a woody stem and thin, flat more veined leaves.
Our milkweed has a soft green fragile stem that oozes milky fluid if bruised. The leaves are wider and thicker. I should find and try to post a picture. see attached but our milkweed in the fields and ditches look different than these pictures too. Maybe they color up more in the fall.
All of the milkweed here has already gone to seed. In my part of Misery bloom usually starts late July/early August, and lasts for most of August. By the time September rolls around all that's left is a bunch of dried up seed pods.
I just went out and checked the ones that we planted on the pond dam in 2019, in hopes that I could grab some seed to share. It has dropped already, but I did find this little guy happily munching away.
