Judy sent me this interesting and important article about Asclepias curassavica (opens in new tab). Apparently, it hosts a parasite to Monarch butterflies and doesn’t always die at the right time in fall, potentially confusing migrating Monarchs. Use the regional native butterfly milkweed (Asclepias tuberosa) instead!
Native to the very local area is definitely the way to go. Our insects appreciated it!
There are so many pretty natives. Might as well use them i say.
