[2][3] 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 in sandy areas such as dunes and savannas.[4][5]. It requires very good drainage and does not appreciate having wet feet for any extended period of time. This decline has in turn been deemed one of the primary causes of the decline of the Karner blue butterfly. [citation needed] One reason this occurs is that lupine seed coats are so tough that only pressure changes due to rapid heating or abrasion are strong enough to allow water to penetrate and start germination. The blooming period occurs from late spring to early summer and lasts about 1 month for a colony of plants. [2][5][11], Human development has eliminated a large portion of its viable habitat. perennis, Lupinus perennis f. perennis, Lupinus nuttallii.

Seed is oval with a light hilum. Remaining habitat is often fragmented, which is problematic for the lupine because it limits the range over which it can reproduce. The main threats to Lupinus perennis are thought to be habitat loss, habitat fragmentation, and poor management. [10] Leaves that have been fed on by Karner blues have distinctive transparent areas where the larvae have selectively eaten only the green, fleshy parts. Dominant canopy trees in some of these habitats are either oaks (especially Black Oak) or pines. Lupinus perennis The blue spires of Lupine are a welcome sight in late spring and early summer.

Lupinus perennis is used as foodplants by the caterpillars of several lepidoptera.  Widsconsin Edible Plants-Eat On The Wild Side Lupinus perennis Benefits: Sun Shade: Bloom Time: Late Spring/Early Summer Zones: 3, 4, 5 Soil Conditions: Sand Soil Moisture: Dry Color: Blue Fragrance: No Height: 1 - 2 feet Spacing: 1 foot. Individual flowers are about ¾ inch long, consisting of 5 blue-violet petals (rarely white or pink), a tubular calyx with large lobes, several stamens, and a pistil with a single style. [3] Petioles are longer than leaflets; stipules are very small. Alternate compound leaves occur along the stems; individual leaves are palmate with 7-11 leaflets. The flowering stalks are light green to reddish purple. [6][7] Lupinus polyphyllus is not native to eastern North America, but has naturalized in areas in the upper Midwest and New England. Viable lupine habitat is often difficult to maintain because it flourishes after fires and other forms of disturbance.

[citation needed] Moreover, fires, feeding by large ungulates, and mowing can improve habitat quality for established lupines by changing soil quality, vegetative structure, and leaf litter depth. The flowering stalks, calyces, and pedicels are sparsely to moderately canescent-hairy. There are over 200 wild species of lupine, and most are North American natives.
