Overview
Artemisia canescens is a semi-woody, shrubby perennial in the Asteraceae family, growing 12–24 inches (30–60 cm) tall and 12–18 inches (30–45 cm) wide with a compact, mounding habit. Stems are erect to ascending, woody at the base, densely covered in white-grey tomentose hairs that give the entire plant a silvery-grey appearance. Leaves are small, 0.5–1.5 inches (1.5–4 cm) long, pinnately divided into narrow, linear segments, silver-white due to dense tomentum on both surfaces. The foliage is aromatic when crushed, with the characteristic bitter-camphoraceous scent of the Artemisia genus. Flower heads are small, inconspicuous, 2–3 mm across, yellowish, borne in narrow terminal panicles in late summer — the species is grown for foliage rather than flowers. The silvery, finely textured foliage contrasts with green-leaved garden plants and retains its colour year-round in mild climates. Native to dry, calcareous habitats in southern Europe. Tolerates drought, poor soil, and alkaline conditions, but declines in wet, heavy clay or in shade, where the silvery pubescence thins and plants become lax. Short-lived — individual plants typically persist 3–5 years. Propagation is by semi-ripe cuttings in summer.
Native Range
Artemisia canescens is native to southern Europe, from the Iberian Peninsula east through southern France, Italy, the Balkans, and into Turkey. It occurs on dry, rocky, calcareous slopes, garigue, and open stony ground at low to moderate elevations.Suggested Uses
Planted in gravel gardens, Mediterranean-style borders, rock gardens, and raised beds, spaced 12–15 inches (30–38 cm) apart. The silvery foliage contrasts with dark green or purple-leaved companions such as Salvia officinalis 'Purpurascens' and Sedum. Effective as low edging along paths in dry, well-drained sites. Tolerates coastal exposure and alkaline soil.How to Identify

Bloom Information
Small yellowish flower heads 2–3 mm across are borne in narrow terminal panicles from August through September. Flowers are inconspicuous and wind-pollinated. The species is grown for its foliage; flower stems can be removed before bloom to maintain a compact form.Detailed Descriptions

Care & Maintenance
Care Guide
Plant in full sun in sharply drained, lean, neutral to alkaline soil with a pH of 6.5–8.0. Space 12–15 inches (30–38 cm) apart. Amend heavy soils with coarse grit and gravel to ensure drainage. Do not fertilise — rich soil promotes lax, floppy growth and reduces the silvery pubescence. Water sparingly after establishment; the species is drought-tolerant and resents summer irrigation in humid climates. Mulch with gravel or stone chips, not organic material. In the Pacific Northwest, site on a south-facing slope, raised bed, or gravel garden to ensure adequate drainage during winter wet periods. Replace plants every 3–5 years as they become woody and open at the base.Pruning
Shear plants back by one-half to two-thirds in early spring (March–April) to maintain a compact, dense mound and prevent legginess. Remove flower stems in late summer if the flower display is not desired — this redirects energy to foliage production. Do not cut into old, leafless wood, as regrowth from bare stems is unreliable.Pruning Schedule
