Echinacea purpurea ‘White Swan’

3 Photos


Echinacea purpurea ‘White Swan’, introduced by Thompson & Morgan in 1987, has large white flowers with orange cones.  This cultivar was comparable to other white-flowered Echinacea in our trial including Echinacea purpurea ‘Fragrant Angel’ but did not perform as well due to disease susceptibility. Yellowing foliage and green deformed flowers, telltale signs of aster yellows, was observed in this cultivar and infected plants were removed.
