Green Comet Milkweed

Comments:  Green comet milkweed is also commonly called short green milkweed. This milkweed can be distinguished from the other milkweeds in Northwest Indiana by its lack of horns on the flower.  Tall green milkweed (Asclepias hirtella) does not have horns either, but tall green milkweed has alternate leaves whereas green comet milkweed usually has opposite leaves.  Green comet milkweed is usually relaxed or reclining with the flower heads leaning instead of erect.

Etymology: The genus Asclepias was named by Carl Linnaeus after the Greek god of medicine, Asclepius. The name, viridiflora, comes from the Latin word, viride, which means "green" and flora which means flower thus meaning "green flower".
