HABITAT & HARDINESS: Echinacea purpurea occurs in the eastern United States from New York and Pennsylvania west to Wisconsin and Iowa. The range extends south to the Florida panhandle, Louisiana and Oklahoma.
The parent species is indigenous to open woodland edges and clearings, savannas, moist to mesic blackland prairies, meadows, limestone glades and roadsides.
The ‘Powwow White’ cultivar is a PanAm Seed selection that is reported to be faster to flower, shorter in height and more floriferous than other seed grown varieties.
Plants are hardy from USDA Zones 4-9.
PLANT DESCRIPTION: Echinacea purpurea ‘Powwow White’ is an upright branching perennial.
Stems are sturdy and pubescent with leathery oval or lance shaped leaves. The blades are deep green with scattered teeth and a short winged petiole.
Flower heads are 3-4” across and are held above the foliage. Each daisy-like head has white overlapping rays. The ray florets arch downward and surround a robust spiny golden cone loaded with disc florets.
Flowering begins in late spring and continues for about a month. Plants occasionally rebloom in autumn. Prickly clusters of dark achenes form from the disc florets and remain into early winter.
This compact plant grows 16-20” tall with 12-16” spread.
CULTURAL & MAINTENANCE NEEDS: The ideal site for Echinacea purpurea ‘Powwow White’ has full sun and fertile well drained soil. Plants tolerate part sun but are less floriferous.
Established plants endure heat and some drought. Plants are pest resistant and unpalatable to deer and other herbivores.
This is a sturdy cultivar with strong stems that do not need staking.
Deadheading will extend the season of bloom. However, seed heads provide winter interest and desirable seed that are savored by goldfinches.
LANDSCAPE USES: This is a good choice for as an Accent for a Wildlife Garden or Cut Flower Garden. Due to the compact growth this cultivar is a useful container plant. Plants are also used as Butterfly Nectar Plants or as part of a Grouping or Mass Planting.
