Yarrow Lawns

Yarrow is a great choice for a low-water alternative to a traditional lawn.

Common Yarrow (Achillea millefolium) grows naturally in meadows throughout the northern hemisphere. In temperate regions, this herbaceous perennial plant is often found growing in grassy areas and considered a lawn weed. Ironically, in regions with a Mediterranean climate, this is used as a lawn alternative to turf grass. Yarrow is moderately drought tolerant, requiring much less water than a traditional lawn. While not as tough as turf, Yarrow does tolerate light foot traffic.


Yarrow’s botanical name “millefolium” means “thousand leaves”. The fern-like appearance of its foliage is made up of many smaller leaves growing densely along its stems. The soft leaves make for a very comfortable walking surface that feels like walking on soft grass. Some varieties of Yarrow differ in color from gray-green to dark green.

The main body of Yarrow stays quite low (<12” / 0.3m) with flower stalks that rise 2-3ft (1m). Yarrow flowers best in full sun, and plants in shade will either not produce flowers or send out very long shoots to reach the sun. The flowers are very attractive, long lasting and can appear year round. Flowers appear in a cluster of many tiny blooms. Wild specimens typically have white flowers but cultivated varieties can be found in red, yellow, pink and other pastel hues. The flower stalks get woody with age, and should be cut right back to the ground after they are spent. When a tidy lawn is desired, a trim every 6 weeks during the warmer months is the most that is required. The mower will take care of these woody stems but you will have less flowers.

When left to grow naturally, yarrow can be used for a butterfly meadow in a wildlife garden. The downside is that you may experience more die-back and bare patches with no-mow lawns. This is because the plant is putting more energy to growing flowers than spreading via rhizome.


In its first year, Yarrow will require watering twice a week to get established, then reduced to once weekly after the first summer has passed. When grown in temperate climates, Yarrow will not need watering after establishment unless there are abnormally dry periods. For Mediterranean climates, Yarrow will still require watering every 2 weeks as it is only moderately drought tolerant. Yarrow’s natural response to prolonged drought is to die back and regrow in the rainy season. Occasional watering will prevent the die back and keep the yarrow looking lush.

Use As a Lawn

Yarrow can handle foot traffic but is nowhere near as resilient as a turf lawn.  If you expect the area to experience a lot of foot traffic, it will not hold up as well as turf so you may want to consider a native grass instead. Yarrow grows more dense and prostrate when regularly mowed and will have a greater tolerance to wear from foot traffic. You can expect to use half the amount of water to irrigate a yarrow lawn and spend 80% less time on mowing.

Due to it's spreading growth by rhizomes, a yarrow lawn needs to be held in it's area with edging to prevent spread into nearby flowerbeds.

The only real disadvantage to using Yarrow for a lawn is that you may not be able to find a lawn service that is willing  to maintain it. As it requires much less maintenance than a normal lawn, this is not a big burden on a homeowner.

Planting a Yarrow Lawn

When choosing to plant a yarrow lawn in a Mediterranean climate, try to source yarrow supplied from a native nursery. Common Yarrow has a wide range and many of the specimens sold in nurseries are bred from European stock which may not be as adapted to drought as local cultivars.  You can start the lawn by seed, or you can plant small plants in a grid spaced 6" (15cm) apart. Unlike many grasses, Yarrow is not easily found sold as plugs or as rolled turf. Yarrow is a reliable self-seeder, so shake the flower heads after cutting to spread the seeds across the lawn. Yarrow is also available in hybrid forms and these plants are bred to be non-spreading so be sure to source the millefolium species. Other species in the Achillea genus tend to be better suited as individual plants for flower beds, not as a lawn.

Yarrow is a versatile plant, growing in shade and full sun, and does not need any fertilizer as they flourish in nutrient-poor soil. As an evergreen plant, it will remain verdant year round as long is it is not drought-stressed. The only real pest that can be troublesome are rabbits. Local bunnies will enthusiastically nibble away at  yarrow leaves but will not dig out the roots, so the plants will recover and grow back once you have prevented the rabbits from trespassing your lawn.

Other uses for Yarrow

Yarrow flowers are long lasting when cut, and are well suited for use in floral bouquets.

Yarrow (Achillea millefolium) was named after Achilles, the Greek mythical hero who's army used yarrow to heal wounds. Today, Yarrow is a popular herbal remedy. Yarrow contains flavonoids, chemicals that can increase saliva and stomach acid to aid digestion. Tannins in the plant have an astringent effect, which is why it has been historically used for healing wounds.
