Are you wanting native milkweed that grows in the southern states? I have many on my property. I do not mow them down because I want butterflies. Where do you live? I am in western KY

Yes,they would be native. I did have the plant but it was killed during the winter,and I gave away my last seeds past winter. So now I have to start again.

I am funny with MilkweedFarm,not all the seeds I get from him sprout? Think he sells dead seeds too?

I can trade poke milkweed for threadleaf sundew if oyu are still needing some. What size trade were you wanting? 1#? 2# Or do you trade by the plant?
