Achillea ptarmica

Type:

Herbaceous perennial

USDA hardiness zones:

3-9

A profusion of button-like, pure white, 1/2\ wide, double flowers resembling pompons in large branched heads on stems up to 2 feet. Unlike most other yarrows, this species features lance-shaped leaves which are neither deeply dissected nor fern-like in appearance. Excellent cut and dried flower. Tolerant of summer heat and humidity. Over time, a number of Achillea ptarmica clones or seed-raised plants with double flowers have been sold under the cultivar name of 'The Pearl' resulting in what should more accurately be referred to as a group, namely, The Pearl Group."
