White Sagebrush

White sagebrush is a North American herbaceous perennial with upright, softly hairy stems and aromatic, lance-shaped leaves that read silver-green in the garden. It grows about 2–3 feet tall and wide in cultivated settings, forming clumps that can expand through rhizomes. Small yellowish-gray flowerheads are subtle rather than showy and generally appear from summer into fall. ## Growing Conditions Plant it in full sun and well-drained soil. It tolerates dry to medium moisture and poorer soils once established, while persistently wet ground can cause root rot. North Carolina Extension lists USDA zones 4a–10b; the current catalog range of 4–9 is retained because regional climate and source conventions vary. This plant fits native-style, prairie, and dry garden settings where its silvery foliage can contrast with green grasses and flowering perennials. ## Spread and Seasonal Care Rhizomes and occasional self-seeding can let the species expand beyond its original clump. Give it room in naturalistic plantings and divide or use a root barrier where a tighter boundary is needed. Foliage may decline or stems may flop later in summer, particularly in humid or moist conditions. The [NC State Extension profile](https://plants.ces.ncsu.edu/plants/artemisia-ludoviciana/common-name/white-sagebrush/) describes cultivation and garden behavior; the [US Forest Service review](https://research.fs.usda.gov/feis/species-reviews/artlud) documents its broader seasonal and ecological range. ## Maintenance Water new plants while they establish, then adjust supplemental water to rainfall and soil. Remove tired stems after flowering or divide clumps when they outgrow their space. Keep drainage sharp and monitor rhizomatous spread near smaller plants or paths.
