From the VA Native Plant Society--"Natives are Glamorous Plants"

"There may be some non-natives that are beautiful, too,” Randee said,  “but beauty doesn’t stop with a visual image.   Beauty is in the totality.  So the beauty of Asclepias incarnata includes the beauty of a Monarch butterfly.  Not just a snapshot of a Monarch, but a living, moving Monarch.  Now under that definition of beauty,  I defy anyone to come up with any non-native that is more beautiful than Asclepias incarnata. ”"
