Achillea 'Double Diamond'

Achillea ptarmica
Sneezewort or White Tansy were common garden flowers as early as 1629 in England when Parkinson's description of the leaves "hackt about the edges like a sawe" explains the old name Goose-Tongue. Today, we love it for its easy care, deer and rabbit nixing aromatic leaves, and generous cut flowers composed of pearly rosettes on uplifted stems.

PLACEMENT & CULTIVATION
The frilly pompon pure-white flowers of Achillea 'Double Diamond' are excellent as cut flowers. This variety spreads modestly, sending out roots that run just under the surface. To renew this short-lived perennial, it's recommended to divide it every three years. It's a valuable low-maintenance perennial for garden edges and mid-borders in wildflower, cut-flower, and cottage gardens. The flowers attract pollinators, and the aromatic leaves repel deer and rabbits. However, they may also cause skin irritation, so handle with care.
Final Spacing:
1-2'
Water Requirements:
Medium Water Use
Watering Details:
While somewhat drought tolerant, this plant does best with added water during dry spells. Do not over water.
Soil pH:
Prefers acidic to neutral soils.
Fertilizer:
Mix in about 2" of compost prior to planting. Apply a thin layer of compost each spring. Do not over-fertilize, as this will cause floppy, leggy stems.
Diseases & Pests:
No major pests or diseases. Powdery mildew and root rots are possible in shady, wet conditions.
When to Cut for Bouquets:
Harvest when flowers are fully open.
