Artemisia filifolia aka Sand Sage

Artemisia filifolia is a shrub in the aster family. Its names include sand sage and sand sagebrush. It grows wild across west-central and central parts of the United States. Its range extends south into northeastern Mexico. It lives on sandy ground in deserts and dry plains. These habitats lie within its temperate native range.

The shrub branches freely and forms a rounded crown. In gardens, one source gives a height of 4 feet [1.2 metres]. That source gives a spread of 1.6 feet [0.5 metres]. Other accounts report heights of 5–6 feet [1.5–1.8 metres]. Growth is moderate. The plant may keep or shed its leaves, depending on conditions. Drought can cause some leaves to fall. Young stems are thin, silver-grey, and covered with fine hairs. Older stems turn grey-brown. The bark splits lengthwise and peels into strips.

The leaves are silver-green and have a faint scent. Fine hairs cover both sides. They sit directly on the stems, with no leaf stalk. Leaves alternate along the stems but often cluster at nodes. Their shape is narrow, though some have three slender lobes. Small yellowish flowers grow in heads along tall, upright spikes. They appear from late summer into early winter. Some flowers contain both male and female parts; others do not. Wind carries the pollen. The fruits are tiny achenes with faint ribs.

Grow sand sagebrush in a warm site with full sun. It also tolerates light shade. It needs soil that drains well. Sandy or loamy soil suits it. Neutral to mildly alkaline soil is suitable. Established plants withstand drought, though the species also accepts moist soil. Poor, dry soil helps plants live longer and strengthens their scent. Plants For A Future lists USDA zones 3–7. It describes the species as easy to grow. Seed and half-ripe cuttings offer ways to raise new plants.

This shrub suits planted beds and land restoration work. Its roots help hold loose sand against wind erosion. Restoration projects use it on rangeland and former coal sites. Soft leaves have served as a toilet-paper substitute. No edible uses are recorded. Reported folk uses include preparations for indigestion, boils, and snakebites. These reports do not establish treatment safety or effectiveness. Plants For A Future records no toxicity reports for this species. It flags weed potential without stating its severity.
