I'm glad everyone is planting milkweed this year!
I have seen A. tuberosa seeds here at Home Depot and Lowe's and that's a native variety. But they also sell A. curassavica plants which is Tropical Milkweed and not native. Plus, research has found it contributes greatly to the spread of the OE spore in the more southern states where the plant does not die back. If you don't want to rip yours out like I did, just make sure you cut it back during the winter and keep the new growth off of it! This will keep those darn Monarchs from laying their eggs during the winter season!
Plus, it's good to cut your plants back, anyway. Makes them bushier, and usually gets rid of the milkweed aphids and bugs (at least for a while). A fresh start, if you will.
