The Pearl Brideflower

Achillea ptarmica (The Pearl Group)

Plant Details:

Plant Type: Perennial
Plant Family: Asteraceae
Plant Description: A group of double-flowered cloned yarrow unlike most other yarrow species. Green leaves are not fern-like or dissected but lance-shaped and finely toothed. Profuse, white, button-like flowers bloom throughout the summer. Tolerant of many soil types and drought.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
