Hardiness of Tropical MW
I'm three years into butterfly gardening and hand rearing cats. While I want to increase habitats for as many species of MW as I can, tropical milkweed has been the most easy to grow and reliable food source for my hordes of hungry cats. Will definitely double or triple my tropical MW next year.
However, here's a hiccup: the temps here in SW PA are dropping into the mid 40s tomorrow. Is tropical MW hardy enough to withstand that temperature? Will my tropical MW be okay, or will I have to pot it all and bring it inside?
