Achillea The Pearl

Achillea ptarmica ‘The Pearl’ is a charming herbaceous perennial prized for its masses of small, double, pure white flowers that resemble tiny buttons or pom-poms. Blooming from late Spring through Summer, these dainty flowers are held on slender, branching stems above dark green, finely textured foliage. A reliable, long-flowering plant, it attracts pollinators and is an excellent choice for cut or dried flower arrangements.

Perfect for cottage gardens, wildflower borders, or informal meadow-style plantings, where its delicate flowers create soft contrast with other perennials. Thrives in full sun to partial shade and grows best in moist but well-drained soil, though it tolerates poorer soils and moderate drought once established. Space plants 30–40 cm apart to allow for clump development.

Reaches a mature height of 60–80 cm with a spread of 40–50 cm, forming a bushy, upright habit.

  • Trimming: Cut back faded flower stems and trim to maintain a neat appearance throughout the growing season. In late autumn or early spring, cut back old growth to ground level to encourage fresh growth.
  • Fertilising: Achillea thrives in low-nutrient soil, so fertilisation is generally unnecessary. If needed, apply a balanced fertiliser sparingly in early spring.
  • Watering: Water young plants during establishment. Once established, Achillea is drought-tolerant and rarely needs additional watering except during prolonged dry spells.
  • Pest Control: Monitor for aphids and spittlebugs. Remove pests by hand or use insecticidal soap as necessary.
  • Disease Management: Watch for powdery mildew (white, powdery coating on leaves), especially in humid conditions. Improve air circulation and water at the base to avoid wetting the foliage. Apply a fungicide if needed.
