Upright yarrow with flat clusters of bright yellow flowers over gray-green feathery leaves

Light

Full sun.

Water

Water weekly the first summer. After that, only in long droughts.

Planting and soil

Plant in spring or early fall, crown level with the soil.

Feeding

None.

Pruning

Cut spent flower stems down to the leaves for rebloom. Tidy up in early spring.

Through the year

Gray-green leaves in spring. Flowers from June, rebloom into late summer with deadheading.

If something's off

Floppy stems mean rich soil, too much water or shade. Powdery mildew in crowded spots. Yarrow is toxic to dogs and cats if eaten.

Plays well with

Plant it with friends.
