Alps yarrow (Achillea distans)
Achillea distans (Alps yarrow) is a medium-maintenance perennial native to Europe, thriving in full sun across Zones 3-8.
Complete Plant Information
Overview
Achillea distans, widely known as Alps yarrow, brings vertical interest and dense, showy floral displays to sunny perennial gardens. This herbaceous perennial is valued for its tolerance to dry conditions once established, making it a reliable choice for xeriscaping or lean-soil locations. It typically forms clumps that spread slowly via above-ground stolons, reaching heights up to 3.25 feet when in full bloom.
Native to the montane and subalpine meadows of central and southeastern Europe, the Alps yarrow is well-adapted to harsh environments. Its finely textured, hairy foliage provides excellent contrast to the flat-topped clusters of pink to white flowers that appear reliably from early summer into mid-summer. While native to distinct ecological niches, Achillea distans maintains rugged appeal in garden settings.
Gardeners appreciate this species not only for its aesthetic qualities but also for its low susceptibility to browsing by deer. Proper placement in full sun with adequate drainage ensures healthy growth, where it contributes robust texture and color without requiring excessive water or rich fertility.

How to Grow
The key to successfully cultivating Achillea distans lies in providing optimal drainage and ample sunlight. Plant this species in consistently sunny locations, aiming for at least six hours of direct sun daily. It performs best when sited in evenly moist to dry, well-draining, sandy loams. Gardeners must actively avoid heavy clay soils and areas prone to standing moisture, as these conditions often lead to root issues.
Maintenance for Alps yarrow is relatively straightforward, classifying it as medium effort. Regular watering is necessary only while the plant is newly establishing its root system. Once mature, water sparingly, allowing the soil to dry out between irrigation cycles, aligning with its dry-to-medium water needs. No routine fertilization is required; in fact, rich soil can encourage weak, floppy stems.
Deadheading spent flower heads consistently will clean up the display and often prompts the plant to produce a secondary flush of blooms later in the season or into the fall. After the main bloom period concludes, cutting the stems back to the basal foliage helps maintain a tidy appearance. Clumps should be divided every three to four years when they become overcrowded, a process that refreshingly rejuvenates the plant.
Landscape Uses
Alps yarrow excels when utilized in mixed perennial borders where its upright structure and airy plumes can add contrasting texture. Its drought tolerance makes it an indispensable component in cottage gardens, especially those designed for sunny, drier beds where many other perennials might struggle. Consider mass plantings near walkways or in the mid-border to maximize the impact of the pink to white summer flowers.
Because Achillea distans handles lean soil well, it serves as an excellent transition plant between hot, dry rock gardens and richer border areas. Pair it with sun-loving companions that share similar cultural requirements, such as Russian Sage (Perovskia atriplicifolia) or sedums, which appreciate sharp drainage. The foliage of plants like ornamental grasses also complements the fine texture of the yarrow.
For a dramatic effect, group several specimens of the Alps yarrow together. This density helps showcase the collective impact of the corymbs of flowers against the backdrop of deep green, finely dissected leaves, creating robust drifts of vertical interest in the sunny season.

Noteworthy Characteristics
Achillea distans, commonly called Alps yarrow, is a stoloniferous, herbaceous perennial native to high altitude, montane and subalpine meadows and rocky slopes in the mountains of central and southeastern Europe. This plant has escaped cultivation and can be found in parts of Australia, western Europe, and the United States. Mature plants will reach between 2-3.25’ tall and spread via above ground stolons to form clumps around relatively equal width. The hairy leaves are ovate to lanceolate with finely textured, doubly pinnate lobes and will reach between 1.5-5” long and 0.5-1” wide. The stems are topped by terminal inflorescences in spring and summer. The dense corymbs of small, pink to white flowers can reach up to 4” across.

Potential Problems
While generally robust, Alps yarrow can occasionally be affected by fungal issues, specifically rust, powdery mildew, and stem rot. Stem rot is almost always an indicator of overwatering or poor soil drainage; ensure the planting area is amendable to sandy loam rather than heavy, water-retentive clay. Managing airflow and avoiding overhead watering during humid periods can mitigate mildew and rust issues on the foliage.
If the plant develops weak stems that flop or become matted after heavy rain or wind, a simple solution is to cut the stems back hard to the basal leaves. This practice tidies the plant immediately and encourages a compact, more manageable new flush of growth, although it may sacrifice any remaining blooms. Deer typically browse other plants before addressing the foliage of Achillea distans.
Frequently Asked Questions

Achillea distans is hardy across a wide range, performing reliably in USDA Zones 3 through 8.
How large does Alps yarrow grow?
This herbaceous perennial typically reaches a mature height between 2 and 3.25 feet tall, spreading to a similar width of 2 to 3 feet via stolons.
What sun exposure does Achillea distans need?
Alps yarrow requires full sun to maintain dense habit and prolific flowering, making it ideal for the hottest, brightest spots in the garden.
When does Alps yarrow bloom?
The bloom time for this species is characteristically late spring through mid-summer, generally occurring from June to August, presenting attractive pink to white flower clusters.
Conclusion
The reliability and drought tolerance of Achillea distans make it a cornerstone for sunny, low-intervention garden design. Providing pink to white blooms through summer, this Alps yarrow offers excellent texture and proven hardiness across most temperate climates. Check that your garden’s sun exposure and soil drainage match its requirements before planting this handsome perennial.
Companion Planting
When planning placements alongside your Achillea distans, focus on other Mediterranean or dry-tolerant herbs and perennials. Lavender (Lavandula spp.) is an excellent partner, sharing a love for full sun and sharp drainage, while providing complementary purple coloration to the white or pink hues of the yarrow. Catmint (Nepeta spp.) also pairs well, offering soft blue flowers that contrast nicely with the fine leaf structure of the Alps yarrow.
Consider using low-growing stonecrops (Sedum) as groundcovers beneath taller specimens of Achillea distans. This helps suppress potential weeds in the drier areas the yarrow prefers, while also visually buffering the space between taller flowers and the ground. Ensure that any companion plants do not require consistent moisture, as this will work against the optimal growing conditions for this drought-tolerant species.
Propagation Tips
The primary method for propagating Achillea distans is through division, best performed in early spring or early autumn before harsh weather sets in. Carefully dig up established clumps (every 3-4 years) and separate them into smaller, viable sections, ensuring each division has a healthy crown and sufficient root mass. These divisions can then be replanted immediately at the same depth they grew previously.
While division is excellent for maintaining established cultivars, species plants, like the native Achillea distans, can also be propagated via seed. Sow fresh seeds thinly on a moist, well-draining seed starting mix, keeping them just barely covered. Germination often requires specific cool stratification periods, mimicking natural mountain conditions, so research stratification techniques before attempting seed propagation.
