Description
Achillea millefolium Cassis, also known as Yarrow, is a perennial plant appreciated for its dense and vigorous growth, heat and drought resistance, and vibrant cherry red flowers. It has a long and abundant flowering period, from summer to autumn. This plant is low-maintenance, highly ornamental, perfect for quickly covering slopes, dressing borders, or creating beautiful wild bouquets. Exuberant and undemanding, this garden favorite adds a nostalgic charm to unpretentious flower beds. Resistant and easy to cultivate in all regions.
Achillea millefolium Cassis is a perennial plant with stoloniferous growth habit, forming compact and upright tufts from spring onwards. It belongs to the Asteraceae family. It is one of the many cultivars of Achillea millefolium native to Europe and Asia Minor. The plant reaches a height of 65 cm (26in) when in bloom, with foliage measuring 20 to 30 cm (8 to 12in). It spreads over 50 cm (20in) or more. The inflorescence is a flattened corymb, 8 cm (3in) in diameter. The remarkably long flowering period extends from July to October. The flowers are actually heads, with tubular disc florets in the central part, while the peripheral florets are ligulate. These heads, appearing at the tops of stems, form flat or slightly rounded corymbs, intensely coloured in cherry red. They give rise to fruits called achenes. The stem is channelled and villous. The foliage is deciduous or semi-evergreen, aromatic and finely dissected into narrow strips. The leaves are bipinnately lobed, feathery, and dark green in color, with a matte finish. The plant spreads across the ground surface through stolons, allowing it to colonise large areas.
Achillea millefolium Cassis integrates well in rock gardens, on top of walls, as a border plant, or on slopes where it helps prevent erosion. This stoloniferous plant can be used as ground cover on large surfaces, eliminating the need for lawn mowing in low-traffic areas. It tolerates competition from tree roots, making it a good groundcover choice for woodland edges. As it is easy to cultivate and withstands drought well, it is perfect for dressing the base of shrub roses or bordering a sunny flower bed.

Planting and care
Sow Achillea millefolium seeds from February to June or from September to October on the surface of good potting soil and cover the seeds with a thin layer of vermiculite compost. Place in a mini-greenhouse at a temperature of 15-24°C (59-75.2°F) or enclose the seed tray inside a polyethylene bag until germination, which usually takes 1 to 3 weeks. Keep in the light as it facilitates germination.
When the seedlings are large enough to handle, transplant them into 8 cm (3in) pots and grow them in cooler conditions. When the plants are well-developed and all risk of frost has passed, gradually acclimatise the plants to outdoor conditions for 10 to 15 days before planting them outside. Transplant the plants at a distance of 60cm (24in) in well-drained soil in full sun. September sowings will overwinter in a cold frame and be planted outside the following spring.
Plant Achillea millefolium in any soil, even chalky, dry or moist but well-drained. It can even adapt to clay soils if they are healthy and well amended. It will grow in partial shade but prefers full sun. In cooler climates, planting can be done all year round. In regions with hot and dry summers, it is preferable to plant in September-October so that the plant can establish its roots during autumn and winter to withstand the following summer. It is advisable to cut back all vegetation at the end of the season to encourage the growth of new shoots in spring.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
