Pow Wow Wildberry holds a deep rose-purple that stays saturated from the first flowers in June through the last ones in fall. Echinacea purpurea Pow Wow Wildberry grows 20 to 24 inches tall and 12 to 16 inches wide in full sun to part sun, hardy from Zone 5 through Zone 8, and blooms the first season after planting.
Flowering starts in early summer and continues into fall, heavy across the whole plant because it branches freely and sets buds along the stems rather than only at the tips. It reblooms without needing deadheading, though cutting spent flowers keeps it tidier.
Leave the last seedheads standing when the season ends. Goldfinches strip them through late fall and winter, and the dark cones hold their shape under snow.
The compact size fits a container, a front-of-border planting, or a mass planting. Purple coneflower takes drought, heat, humidity, poor soil, and clay once established. Full sun gives the sturdiest stems and the heaviest bloom. Deer generally leave it alone.
