Goosefoot violet

Description

Viola purpurea is a species of violet which bears yellow flowers. It is known commonly as the goosefoot violet. It is a small plant which bears thick to fleshy toothed or ridged oval leaves which are mostly green but may have a purplish tint to them. The flowers are made up of bright yellow petals, the lowermost being streaked or veined with purple and the lateral petals with purplish undersides. There are several subspecies, most of which are known by the common name goosefoot violet. These subspecies are found across the western United States from Wyoming to California. It is a member of the chaparral plant community and the foothills and low elevation mountains. Viola is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some Viola species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and flowers appear to rise from the ground. The remainder have short stems with foliage and flowers produced in the axils of the leaves (axillary). Viola typically have heart-shaped or reniform (kidney-shaped), scalloped leaves, though a number have linear or palmate leaves. The simple leaves of plants with either habit are arranged alternately; the acaulescent species produce basal rosettes. Plants always have leaves with stipules that are often leaf-like. The flowers of the vast majority of the species are strongly zygomorphic with bilateral symmetry and solitary, but occasionally form cymes.
