It is noted for attracting wildlife.
Suitable for: light , medium and heavy soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic soils and can grow in very alkaline soils.
It can grow in semi-shade or no shade. It prefers dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure.

Landscape Uses:Container, Ground cover, Massing, Seashore, Woodland garden. Succeeds in most soils and situations but prefers a well-drained soil in a sunny position. Shade tolerant. Plants live longer when grown in a poor soil and also do well on lime. Established plants are very drought tolerant, they can show distress in very severe droughts but usually recover. It remains green after grass has turned brown in a drought. Plants succeed in maritime gardens. The plant has a very spreading root system and is usually quite invasive. A very hardy plant, tolerating temperatures down to about -25°c. Yarrow is an excellent plant for growing in lawns, meadows, orchards etc., it is tolerant of repeated close cutting and of being walked on. It works to improve the soil fertility. A very good companion plant, it improves the health of plants growing nearby and enhances their essential oil content thus making them more resistant to insect predations. There are some named forms, selected for their ornamental value. 'Pink' has very aromatic foliage and deep pink flowers. Hybridizes freely with other members of this genus. A good bee plant, it is an important nectar source for many insects. Special Features:
Attractive foliage, Edible, Fragrant foliage, Invasive, Naturalizing, Attracts butterflies, Suitable for cut flowers, Suitable for dried flowers. The plant is heat tolerant in zones 9 through 1. .
At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 to 12 .
For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture information on the habit and root pattern is also useful and given here if available. The plant growth habit is a runner spreading indefinitely by rhizomes or stolons . The root pattern is fibrous dividing into a large number of fine roots . The root pattern is rhizomatous with underground stems sending roots and shoots along their length .
