Summary

Eremogone kingii, commonly known as King’s Sandwort or Mountain Sandwort, is a perennial herb native to the mountainous regions of Western North America, including the Rocky Mountains and the Great Basin. It is typically found in rocky slopes, meadows, and talus habitats within subalpine and alpine zones. King’s Sandwort grows at a moderate rate to a height and width of 0.5-1 feet (0.15-0.3 meters). The plant forms tufts of narrow, linear leaves and bears clusters of star-shaped white flowers that bloom in the summer, adding a delicate touch to rock gardens and alpine collections.

King’s Sandwort is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it a suitable choice for rock gardens, xeriscaping, and naturalized areas. Its low water requirement and preference for full sun make it an easy plant to maintain in suitable climates. While it is not commonly affected by diseases, it can suffer from root rot if grown in poorly drained soils. Gardeners should be aware that it may require protection from excessive winter moisture in colder regions.CC BY-SA 4.0
