Kelseya is a monotypic genus of flowering plants belonging to the family Rosaceae. The only species is Kelseya uniflora.[1] It is commonly called the oneflower kelseya, spiraea or alpine laurel.[2][3] The genus was named in honor of Francis Duncan Kelsey, a Montana resident botanist, who discovered the plant in 1888 at the "Gate of the Mountains" near Townsend.[4][5]

Kelseya uniflora is a perennial limestone endemic[2] that grows in cracks of volcanic and limestone outcrops at 1500-3500m elevation.[6][3] It is native in 3 states in Northwestern USA: Idaho, Montana and Wyoming.[2] It typically grows as a solitary plant in a sun-exposed position as a ground covering subshrub. This species has also been reported in riparian woodland but this should be considered an outlier.[7][8]

This species rarely measures more than 10cm tall but often achieves 1m or more in diameter.[2][6] Their habit is an adaptation to the wind-blast exposed rocky ridges they grow on alongside cushion plant communities.[9] Plants branch into numerous slender stems that are densely covered with imbricated leaves. The leaves are light to greyish green, leathery and hairy, ovate-oblong and grow in dense rosettes. Leaves become brownnish to black when withered and remain on the branch to form a hardened protective structure.[3][6]

The flowers are produced very early in spring and are reddish-purple.[10]

From very early on it was clear that these plants formed an outlier group within Rosaceae together with Petrophytum (now Petrophyton) and Eriogynia (now Luetkea) as sections within the genus Eriogynia.[11] After a number of revisions and molecular analysis they are now member of tribe Spiraeeae.[12][13]

The reduction in plant stature and its xeric alpine habitat make it a popular but challenging subject for alpine garden enthusiasts.[14]
