Mariton: Interesting Variant

Yesterday, during the Butterfly Census, we came across this interesting morph of Butterfly Weed(Asclepias tuberosa).  Most Butterfly Weed is orange (as in the photo below), but we found a yellow morph.  In the Plants of Pennsylvania by Rhodes and Block, it lists “flowers yellow to orange-red”, so it probably isn’t as rare we thought.  Photos by Carole Mebus.
