About Potentilla breweri S.Watson
Potentilla breweri S.Watson is a herbaceous perennial plant, or a plant that is nearly a subshrub, that grows from a sturdy, branched caudex. Its leaves are pinnately compound and covered in soft, tangled, woolly hairs, which gives the leaves a roughly silver-blue color. The exact leaf shape and how hairy the plant is can vary a great deal between leaves produced early in the growing season and leaves that grow later in the year. Its inflorescences are cymose, and they usually hold between 2 and 15 flowers. Like most species in the Potentilla genus, its flowers have five bright yellow petals, 15 stamens, and many separate pistils, and the flowers are adapted for generalist pollination. If a flower is successfully pollinated, it will produce a cluster of achenes. This is a taxonomically difficult species that appears to hybridize often with other Potentilla species. The boundaries of the resulting species complex are not well understood. In terms of habitat and ecology, P. breweri grows in high-montane to subalpine meadow openings. It prefers seasonally wet habitats with little competition for sunlight, such as rocky meadows and rock crevices, and it often grows near lakes and streams. It occurs at altitudes ranging from 1,500 to 3,600 metres (4,900 to 11,800 ft).
