Description and Cultural Plant Tips
This California native is a hardy & versatile perennial with fern-like leaves & large, pale pink flower clusters that tolerates dry conditions & low soil fertility better than most other perennials. It it drought tolerant once established. It looks good in a perennial border, rock garden or meadow setting. Some companion plants include Nepeta 'Walkers Low', Coreopsis grandiflora varietals, Hemerocallis varietals, Salvia greggi & Salvia nemorosa.
Select a site that is in full sun. The best time to plant is in early fall to take advantage of winter rains but since this is such a hardy plant it can also be planted in spring or early summer. Achillea can be planted in clay or alkaline conditions as long as the drainage is good. Space plants 1 -2 foot apart & plant so that the root ball is level with the soil surface. Use compost to amend the soil and improve the drainage. Water well & then add 2-3 inches of mulch to the soil surface to retain moisture & control weeds. All yarrows propagate easily from rooted cuttings or division. Spreads naturally by rhizomes. Divide in late fall or early spring. Divide when clumps become overcrowded.
Cut back by half after flowers start to fade to get a 2nd flush in late summer. Cut back in spring for compact plant development.
No significant pests but may develop root rot if drainage is not good. Also needs good air circulation to reduce chance of powdery mildew.
