Are Milkweed Varieties You Buy From Nurseries And Flower Catalogs Actually Toxic To Monarch Butterflies/caterpillars?

Question

I have native milkweed and several “store bought” milkweed plants in my garden. I want to do what’s best for these precious insects. Someone told me that the commercially produced milkweed varieties actually kill monarchs rather than provide a place to breed and lay eggs.

Answer 1

I wouldn't see an issue unless the commercially purchased plants were sprayed with pesticides, or systemics beforehand. Other than this, they should be just fine.
