About Paprika yarrow
Achillea millefolium 'Paprika' · also called Paprika yarrow, Common yarrow 'Paprika' · flowering
Achillea millefolium 'Paprika' is a vivid red-and-yellow cultivar of common yarrow, producing flat-topped corymbs of small, bright cherry-red florets that fade to golden-yellow with age. Extremely drought-tolerant, deer-resistant, and long-blooming from early to late summer. Excellent for pollinators, cutting, and drying. Thrives in lean, well-drained soils in full sun.
Preferred mix: Lean to average, well-drained sandy loam or loam; pH 5.5–7.0
Watch for — Flopping stems: Stems become lax in rich soil, shade, or when overwatered. Avoid fertile soils and ensure full sun. Use grow-through supports if flopping is a problem, or plant in groups where neighbouring plants provide mutual support.
Why paprika yarrow needs this mix
Paprika yarrow flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for paprika yarrow: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons paprika yarrow struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives paprika yarrow weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving paprika yarrow in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for paprika yarrow?
Most flowering plants, including paprika yarrow, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for paprika yarrow in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for paprika yarrow covers the timing and technique step by step.
