How to Grow Achillea
'Cerise Queen' from Seed
Vivid cerise-pink in June, warm salmon-rose in August, dusty vintage rose when dried — one of the most generously flowering and most colour-rich perennials you can grow from seed
If 'Ballerina' is the achillea of refinement and restraint, 'Cerise Queen' is its vivid, warm-hearted opposite — a millefolium variety of considerable colour intensity and considerable presence in the summer border. The flowers are borne in wide, flat-topped umbels of deep cerise-pink, each tiny floret packed tightly together into a plate of colour that catches the sun and holds it, glowing with a warmth and richness that few other summer perennials achieve at this height and on this scale. It is a plant of immediate, confident visual impact.
What makes 'Cerise Queen' particularly valuable over the full season is the way its colour evolves. The fresh flowers of June and July are a vivid, saturated cerise-pink. As summer deepens they soften and warm toward a rich salmon-rose. And as the season closes, they fade to a soft, dusty vintage rose-terracotta that is one of the most beautiful and most sought-after tones in dried flower arranging. A single plant thus provides three distinct but equally beautiful colour moods through the season — and an almost inexhaustible supply of stems for both fresh and dried use throughout.

Understanding the Plant
Achillea millefolium 'Cerise Queen' belongs to the common yarrow group — the millefolium achilleas — characterised by their flat-topped flowerheads, finely divided feathery foliage, and spreading rhizomatous habit. It holds both the RHS Award of Garden Merit and the RHS Plants for Pollinators designation, and it is botanically and aesthetically quite distinct from the ptarmica group to which Ballerina belongs.
Where Achillea ptarmica varieties produce upright, clump-forming plants with rounded pompom flowers, millefolium achilleas spread more broadly at ground level, producing wide mats of feathery, aromatic foliage from which flowering stems rise in summer. The flat-topped flower plates of millefolium varieties are broader, more architectural, and function as exceptional landing platforms for pollinators — the nectar and pollen are fully exposed and easily accessible to bees, hoverflies and butterflies.
The Colour Journey
The seasonal colour evolution of 'Cerise Queen' is one of the qualities that makes it exceptional. Freshly cut stems bring vivid cerise to summer arrangements. Stems cut as the colour begins to shift and dried bring the warm, faded, antique tones so valued in naturalistic dried flower arranging. And stems left on the plant age through salmon to a dusty vintage rose-terracotta that is as beautiful in the October border as the vivid fresh flowers of June. Three distinct colour moods from one plant — all of them outstanding.
RHS Award of Garden Merit & Plants for Pollinators
'Cerise Queen' holds both RHS awards — the AGM for consistent garden performance over many years of assessment, and the Plants for Pollinators designation for exceptional ecological value. The flat flowerhead structure provides one of the most accessible nectar and pollen sources in the summer garden for bees, hoverflies and butterflies, making this as important a plant for wildlife as it is beautiful for the gardener.
When & How to Sow
Like all achilleas, 'Cerise Queen' is straightforward to grow from seed once you know the essential rule — do not cover the seed. Achillea is photoblastic and requires light to germinate. This single point of understanding is the difference between success and frustration, and once you have it, growing achillea from seed is genuinely easy.
When to Sow — Your Options
February to April indoors — the recommended option for reliable germination and the longest possible growing season. April to June direct outdoors — perfectly viable once the soil has warmed, though first-year plants are unlikely to flower. Autumn sowing — scatter seed on a prepared seedbed in September or October and allow cold stratification over winter for robust spring germination. All three approaches work well.
Step by step — sowing indoors:
Prepare pots or modules of fine, moist seed compost. Water from below by standing in a tray — surface moisture without overhead watering, which would dislodge seeds. The compost should feel evenly damp but not waterlogged.
Scatter seed thinly on the surface. Achillea seed is very fine — use the tip of a moistened finger to place seed, or tap gently from the packet. Do not cover with compost. Press gently but firmly across the surface to ensure seed-compost contact.
Cover with a clear propagator lid. Light must reach the seed — a clear cover retains humidity while allowing the light achillea needs to germinate. Place at 15–18°C. A heated propagator is ideal; a bright warm windowsill works from March onwards.
Germination in 14–21 days. Achillea millefolium is slightly slower and more variable than ptarmica types — be patient. Keep the compost consistently moist. Once seedlings emerge, remove the cover and move to the brightest available position.
Prick out once large enough to handle. Millefolium seedlings are fine and delicate. Handle by the leaf, never the stem, and use a dibber to ease roots free. Pot into individual 7cm pots and grow on in good light.
Grow on cool and bright. Good airflow and strong light produce compact, sturdy plants. Avoid warm, low-light conditions which produce the drawn, weak seedlings most prone to damping off.
Harden off and plant out from May. Two weeks of gradual outdoor exposure before planting. Space 30–45cm apart in full sun and well-drained soil. Water in well.
Direct Sowing in April–June
Prepare a fine seedbed and scatter seed as thinly as possible — barely pressing onto the surface rather than raking in. Water gently with a fine rose and keep moist until germination. Thin seedlings to 30cm apart once large enough to handle. Direct-sown plants establish with great confidence and, while unlikely to flower in year one, build into vigorous clumps that flower generously from their second season. This is by far the simplest approach for first-time growers.
Growing On Tips
Once established, 'Cerise Queen' is one of the most low-maintenance perennials in the cottage garden. It asks for sun and drainage, gives back months of vivid colour and excellent cutting material, and improves in performance year on year without requiring much more than occasional division.
Sun & Position
Full sun is essential for 'Cerise Queen' — unlike the ptarmica varieties, millefolium achilleas really do need a full day of sun to flower at their best. In partial shade, plants become leggy, flower poorly, and the vivid cerise colour becomes significantly muted. A south or west-facing open border is ideal.
Soil & Drainage
Well-drained, lean to average soil is ideal. 'Cerise Queen' is notably drought-tolerant once established and actually flowers more prolifically in poorer, drier conditions than in rich, fertile soil. Avoid clay and waterlogged soils. Excellent for gravel gardens, south-facing slopes, and any position with free drainage.
Watering
Water young plants during their first season to establish roots. Once established, millefolium achilleas are among the most drought-tolerant cottage garden perennials available — genuinely reliable in dry summers without supplementary watering once the root system is established. Overwatering is more likely to cause problems than drought.
Feeding
Resist the temptation to feed. Achillea in rich, well-fed soil produces lush leafy growth and poor flowers. No feeding is needed in average garden soil. In exceptionally poor or sandy soil a single light dressing of balanced granular fertiliser in early spring is sufficient.
Deadheading
Deadhead spent flowerheads promptly to encourage continuous production of new stems throughout summer. Cut back to a visible side shoot or bud. But — and this is worth knowing — do not remove every fading head immediately. The transitional colours of 'Cerise Queen' as it ages from cerise through salmon to dusty rose are genuinely beautiful. Leave some stems to age naturally for their own sake.
Division
Divide established clumps every three to four years in spring to maintain vigour and manage spread. Lift the whole clump, divide into sections each with healthy roots and shoots, discard the exhausted woody centre, and replant the vigorous outer pieces. Divided portions transplant readily and can be used to expand plantings or given away.
Common Problems & How to Fix Them
'Cerise Queen' is a resilient, long-lived perennial with very few serious problems. Most difficulties arise from one of a small number of straightforwardly avoidable causes.
| Problem | Likely Cause | What to Do |
|---|---|---|
| No germination | Seed was covered | The single most common cause of failure. Resow on the surface at 15–18°C with no covering whatsoever. Keep the compost consistently moist — surface-sown seed is vulnerable to drying out between waterings. Be patient; germination can take up to three weeks and is often variable. |
| Poor or faded colour | Insufficient sun | Millefolium achilleas need full sun for full colour saturation. In partial shade the cerise colour becomes significantly washed out. If the plant is in too much shade, lift and move it in early spring to a sunnier position — achillea transplants readily when handled correctly. |
| Leggy, floppy stems | Too much shade or very rich soil | Ensure full sun. Do not feed with nitrogen-rich fertilisers. Place twiggy pea-stick supports in early spring before stems reach 20cm. In lean, well-drained soil in full sun, 'Cerise Queen' is generally self-supporting at 60–75cm. |
| Powdery mildew | Dry at roots, poor airflow, late summer | Most common in August and September, particularly in dry summers. Water consistently at the base of the plant, not overhead. Improve airflow with correct plant spacing. Remove affected leaves promptly. Generally cosmetic rather than seriously damaging. |
| Spreading aggressively | Rhizomatous spread | Normal behaviour for millefolium achilleas. Divide every three to four years to contain and rejuvenate. Remove unwanted rhizomes in spring when new growth is visible and easy to track. Both approaches are simple and effective. |
| Poor flowering in year one | Normal first-year establishment | Millefolium achilleas flower modestly or not at all in their first year — this is entirely normal and not a sign of any problem. The plant is establishing its root system. Year two performance is almost always significantly better, and year three better still. |
| Colour not as vivid as expected | Seed variation, soil fertility | Cerise Queen grown from seed shows some natural colour variation — most plants will be a rich cerise-pink, but the shade may vary slightly between individuals. This natural variation is part of the charm of seed-grown perennials. Very fertile soil can also reduce colour intensity — lean conditions produce the best colour. |
When to Expect Flowers
Plants sown indoors in February or March and grown on well will typically begin flowering from late June or July in their first year, though performance is usually modest — the root system is the priority in year one. From the second year, established 'Cerise Queen' plants flower with genuine generosity from June right through to September, with the colour evolving beautifully through the season as described above.
Patience in year one is very much rewarded in subsequent seasons. A well-established clump in its third or fourth year, flowering in full sun in lean, well-drained soil, is one of the most striking and most productive perennials in the summer garden — a wide, spreading mound of feathery silver-green foliage crowned with plate after plate of vivid cerise and yielding an abundance of cutting stems throughout the season.
Year One vs Year Two
If your first-year plant flowers modestly or not at all, resist any temptation to dig it up — it is simply doing what millefolium achilleas do in their first season, which is build a root system rather than put energy into flowers. Leave it in place, cut it back in late autumn, and wait. The second-year plant that emerges will be transformed.
Sow indoors from February and plant out in May or June — established plants flower from their second season with increasing generosity, providing vivid fresh colour in summer and beautiful dried stems for autumn and winter.

Cutting & Drying
As a cut and dried flower, 'Cerise Queen' is among the finest perennials available from seed. The flat-topped flowerheads are bold, long-lasting and structurally distinctive — quite different from the rounded pompom forms of Ballerina — and the colour journey from vivid fresh cerise to soft dried vintage rose gives the grower three separate and equally valuable harvest opportunities across the season.
Cutting Fresh for the Vase
Cut when the flowerheads are fully open and the colour is at its most vivid — typically early to midsummer. Cut in the early morning with long stems back to a visible side shoot or bud, and plunge immediately into deep cool water. Condition in a cool, dark place for several hours before arranging. Fresh 'Cerise Queen' typically lasts seven to ten days in the vase and combines beautifully with white Ballerina, blue cornflowers, and the soft movement of quaking grass.
Drying Cerise Queen
Cut for drying just as the flowers reach their fullest colour but before any fading begins — the dried flower will be one or two shades softer than the fresh one, and cutting at peak colour ensures the best result. Strip all leaves from the stems, gather in small, loose bunches of six to eight stems and hang upside down in a warm, dry, well-ventilated space away from direct light. Cerise Queen dries in two to three weeks and the resulting vintage rose-terracotta tone holds for many months — one of the most beautiful and most useful colours in dried arranging.
Three Harvest Moments
The great advantage of 'Cerise Queen' over many dried flower plants is that it offers three distinct harvest windows with three distinct colour results: vivid cerise-pink cut in June or July, warm salmon-rose cut in August, and soft dusty vintage rose from stems left to age on the plant and cut in September. Each has its own distinct character and its own place in fresh and dried arrangements — a single established plant thus provides an entire season's worth of cutting material in three beautifully evolving tones.
Plant Specifications
Three months of colour. Three harvest windows. One remarkable plant.
We think 'Cerise Queen' is one of the most rewarding cottage garden perennials available from seed — not just for the vivid cerise of early summer but for the entire seasonal journey it takes you on, from bold and vivid in June to warm and faded in October. Grow it alongside Ballerina for the complete achillea pairing — white pompom and cerise plate, restraint and abundance — and discover why this genus has anchored the British cottage garden perennial border for centuries. Our Achillea Cerise Queen seeds are selected for reliable germination and strong first-year establishment, with all the colour richness that made this variety an RHS Award of Garden Merit recipient.
