    This is a wonderful milkweed and I have grown it in fairly large quantities in a number of locations. I have found that it tends to be fairly short-lived and will pretty much disappear after 3-4 years. Then it is time to re-plant it. On the other hand, it is one of the Monarch butterfly’s favorite milkweeds.
