Each gardener has one or two plants that despite what they do they won’t be able to grow a particular plant very well. We have tried off and on to grow this species of milkweed in our habitat. We surmise the reason it isn’t happy is that it truly likes to be wet and our habitat is very dry. Not surprising–it’s swamp milkweed! If you have wet to medium wet soil then this species of milkweed is a good fit for your garden.
