Culture is well known to produce great alterations in the appearance of most plants, but particularly in those which grow spontaneously on dry mountainous situations, and this is strikingly exemplified in the present instance, this species of Potentilla, becoming in every respect much larger, as well as much smoother than in its natural state. Vid. Vaill. above quoted.
It is a hardy herbaceous plant, a native of Switzerland, Siberia, and other parts of Europe, and flowers in July.
Linnaeus considers it as an annual; Miller, as a biennial; we suspect it to be, indeed have little doubt of its being a perennial; having propagated it by parting its roots, but it may be raised more successfully from seed.
