On July 28th, 1806, William Clark, co-captain of the Lewis and Clark Expedition, collected this curious plant while exploring Montana's Yellowstone River. Plant hunter and botanist Frederick Pursh called it a "very handsome species" in his Flora Americae Septentrionalis (1813), which described many plants collected by Lewis and Clark. Snow-on-the-Mountain is distinguished by white-edged and veined upper leaves, is now popular in cutting gardens. Snow on the mountain tolerates deer, drought, and poor soils. Recorded and/or collected by Lewis and Clark on their expedition.

Direct sow seeds outdoors after the last spring frost. Soak seeds in warm water for eight hours before sowing to enhance germination. Approximately 15 Snow-on-the-Mountain seeds per packet.
