Growing Conditions

• Light:
  Full sun. Needs at least 6 hours of direct sunlight daily for best flowering and compact growth.

• Soil:
  Well-drained soil. Tolerates poor, sandy, or rocky soils. Prefers neutral to slightly alkaline conditions.

• Exposure:
  Open, sunny sites with good air circulation. Avoid planting in low or overly sheltered spots that retain moisture.

• Drought Tolerance:
  Highly drought-tolerant once established. Avoid overwatering or planting in heavy, wet soils.

Cultivation & Care

• Planting Time:
  Spring or early autumn, once danger of frost has passed or before soil cools.

• Spacing:
  60–90 cm (2–3 feet) apart to allow air flow and natural form.

• Watering & Fertilization:
  Water regularly during establishment; reduce once established. Avoid rich fertilizer—too much can cause floppiness.

• Mulching & Pruning:
  Mulch lightly to suppress weeds. Cut back hard in early spring to 10–15 cm (4–6 inches) to promote bushy growth and flowering.

• Propagation:
  Propagate by softwood cuttings in late spring or by division in early spring.

Seasonal Interest

• Summer:
  Tall, upright stems with clouds of lavender-blue flowers from mid to late summer. Aromatic, finely divided silver-grey foliage.

• Autumn:
  Flowering may continue into early autumn. Foliage remains silvery and ornamental.

• Winter:
  Dried stems can be left for winter interest or habitat; cut back in early spring.

Wildlife & Garden Use

• Wildlife:
  Flowers attract bees, butterflies, and other pollinators.

• Garden Use:
  Ideal for borders, gravel gardens, xeriscapes, and Mediterranean-style plantings. Excellent in mass plantings or as a structural accent.

• Companion Plants:
  Combines beautifully with ornamental grasses, lavender, echinacea, rudbeckia, salvia, and sedum.
