Medium green leaves with PURPLE-RED petioles & stems.
'John Wargo' is a rare and hard-to-find plant from Henry Weissenberger of Long Island, NY. It's a nigrescens seedling with good red petioles and nice, upright form. Better than 'Regal Rhubarb'.
Should be useful if you're breeding for red petioles
