Lupinus perennis
''Lupinus perennis'' (also wild perennial lupine, wild lupine,〔 sundial lupine, blue lupine, Indian beet, or old maid's bonnets) is a medicinal plant in the Fabaceae family. It is widespread in the eastern part of the USA (from Texas and Florida to Maine) and Minnesota, Canada (southern Ontario, Newfoundland and Labrador), and on the coasts of the Arctic Ocean, where it grows on sand hills and roadsides.〔(Biota of North America Program, 2013 county distribution map )〕
==Description==
Sundial lupine only produces leaves in the first year of growth. The leaves are palmately compound, with 7–11 leaflets arranged radially or in a rosette. Their stalks are numerous, erect, striated, slightly pubescent. The leaflets are obovate, with a blunted apex or pointed spear, naked from above, sparsely pubescent from below.〔Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004). ''The ROM Field Guide to Wildflowers of Ontario.'' Toronto:Royal Ontario Museum, p. 270.〕 Petioles are longer than leaflets; stipules are very small, almost missing.
The inflorescence is long, sparsely flowered, sometimes almost verticilate. Flowers can range from blue to pink, but are most often blue or bluish purple. The calyx is silky, without bractlets; its upper labium with a protuberant basis, is integral or weakly emarginate, the lower one is integral, almost twice longer than upper. Floral bracts are styliform, shorter than the calyx, early falling. The corolla is purple or white, three times longer than the calyx. The vexillum is shorter than the wings. The carina is weakly ciliate. Pods are yellow-grayish-brown, with straight lines, necklace-shaped, short and closely hirsute, easy shattered, with 5–6 seeds. Seed is oval with a light hilum.
