Mariton: Interesting Variant

June 26, 2011

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.
