Eutrochium x ‘Phantom’ – Joe-Pye Weed – 1.25-Quart


‘Phantom’ is supposed to be a hybrid of E. maculatum ‘Atropurpureum’ and White Snakeroot (E. rugosum, currently named Ageratina altissima) from Herbert Oudshoorn of the Netherlands. The original cross was backcrossed to the E. maculatum ‘Atropurpureum’  parent for two generations, with ‘Phantom’ selected from the offspring. So it’s about 7/8 E. maculatum ‘Atropurpureum’ and 1/8 Ageratina altissima.
