Phemeranthus sediformis
Also called Okanagan Fameflower, Okanagan Talinum, Fameflower, Okanogan Talinum
Phemeranthus sediformis, commonly called Okanagan fameflower, is a species of flowering plant in the montia family Montiaceae. It is native to the Okanagan Highlands and Kettle River Range in north central Washington state, United States, and south central British Columbia, Canada. Populations are confined to elevations between 800 and 1,500 m (2,600 and 4,900 ft) on south to southwest facing rocky slopes, outcrops, and knolls. The first specimens were collected by John Jeffrey in 1851, but the species was not named until 1933–1934 when a series of three separate papers describing the plant were published. The species is one of Canada's most range-restricted plants. Despite the small native range, it transplants and adapts easily to gardens and has been part of rock garden and alpine garden seed catalogues for a number of years.
Phemeranthus sediformis is distributed along areas of the Columbia Mountains in southwest central British Columbia, Canada, and northern central Washington State in the US. As of 1994, fewer than 20 known populations had been identified encompassing an estimated total area of 8,000 km2 (3,100 sq mi). 7,000 km2 (2,700 sq mi) of this was in British Columbia and only 1,000 km2 (390 sq mi) in Washington. Populations are known as far north as Opax Hill to the northwest of Kamloops. The western-most populations are in the Walhachin area west of Kamloops Lake, while the eastern-most British Columbian populations are above Okanagan Lake. The Washington state populations are located to the east of the British Columbian ones, and are confined to the eastern portion of Okanogan County and northern Ferry County and a total of less than 10 sites are identified in publications, with the southern most sites found to the north of Thirteen Mile Creek. Phemeranthus sediformis is the only member of the genus native to Canada, and one of the most restricted Canadian native plants.
