Artemisia ludoviciana subsp. albula, commonly known as White Wormwood, White Sagebrush, Prairie Sage, Gray Sagewort, or White Sagewort, is a perennial herb native to a variety of habitats in North America, including prairies, plains, meadows, and open woodlands. It is particularly adapted to arid environments and can often be found in areas with calcareous soil. This species grows at a moderate rate to a typical height and width of 2-3 feet (0.6-0.9 meters). It features lance-shaped, silvery-gray leaves that contribute to its distinctive appearance and aromatic quality. The flowers are yellow and rather inconspicuous, blooming in the summer and fall, and are not typically grown for their floral display.

White Wormwood is valued for its drought tolerance, silvery foliage, and aromatic leaves, which can be used in herbal blends. It is often used in xeriscaping, naturalized plantings, and as a filler in borders or herb gardens. This plant thrives in full sun or part shade and prefers medium or fast-draining clay, loam, or sandy soils. It is low-maintenance, requiring minimal water once established, making it suitable for gardens with low water availability. While generally disease-free, it can occasionally suffer from root rot if overwatered or planted in poorly draining soils. It is also resistant to deer and rabbits, adding to its appeal for gardeners dealing with wildlife pressure.CC BY-SA 4.0
