Silver sagebrush

Also known as: Bolander silver sagebrush

The type specimen of Artemisia cana was described informally by its collector Meriwether Lewis (collected on Fall 11804 in the vicinity of Centinel Creek in South Dakota during the epic Lewis and Clark Expedition) in the following passage from Original Journals of Lewis and Clark edited by Thwaites in 1904 :

Growth Rate

The silver sagebrush exhibits a moderate growth rate during spring, summer, and fall. The tempered speed leads to healthy, even growth patterns and enhances its drought tolerance. In spring, an increased surge of growth is noticeable, producing denser foliage. During summer and fall, the plant continues to grow while maintaining its compact shape and silver hue.

Water: Originating from arid regions, silver sagebrush exhibits strong drought tolerance, requiring watering every 2-3 weeks. It thrives outdoors in well-draining soil that prevents root rot, mimicking its native habitat and optimizing water use efficiency.

Fertilize: For silver sagebrush, apply balanced fertilizers annually in early spring to encourage growth. During active growth, use high nitrogen fertilizers sparingly. Older plants need adjustments in quantity. Monitor soil since silver sagebrush prefers minimal intervention; over-fertilization can weaken growth. Follow manufacturer's dosage guidelines.

Pruning: Silver sagebrush benefits from early spring pruning to enhance growth and shape. Remove dead branches for better air circulation. Light pruning promotes density, while severe pruning rejuvenates older specimens. Limit cuts to one-third at a time to reduce stress, ensuring silver sagebrush thrives in the garden.

Propagation: Silver sagebrush is resilient and adaptable, thriving from stem cuttings. Make angled cuts for better rooting, plant in well-draining soil with partial sun, and maintain consistent moisture without waterlogging. Rooting hormone can improve success rates but is not essential.
