The vexillum is shorter than the wings. Lupinus perennis subsp. Scientific Classification. The leaves are palmately compound with 7–11 leaflets arranged radially. 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. [2][5][11], Human development has eliminated a large portion of its viable habitat. Russel hybrids (Lupinus Russell hybrids) grow quickly to 3 to 4 feet tall with large spikes of flowers the first season. The leaflets are obovate, with a blunted apex or pointed spear, and sparsely pubescent. The flowering stalks, calyces, and pedicels are sparsely to moderately canescent-hairy.

If you shake them, the seeds rattle. perennis, Lupinus perennis f. perennis, Lupinus nuttallii. Saved seeds from this hybrid plant will not grow true or bloom well. The calyx is light green to reddish purple. Rich in nectar, they are attractive to butterflies, hummingbirds and many pollinators. [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. The wild lupine will grow best under dry conditions, and in full sun, but will tolerate part-sun. The root system consists of a taproot with rhizomes. The root system can fix nitrogen into the soil. [3] Petioles are longer than leaflets; stipules are very small. Habitats include sand prairies, openings in sandy woodlands, sandy savannas, edges of sandy woodlands, stabilized sand dunes, and powerline clearances in sandy areas. These usually have blue, white, or yellow flowers. Alternate compound leaves occur along the stems; individual leaves are palmate with 7-11 leaflets. Grow in organically rich, moderately fertile, slightly acidic, evenly moist, well-drained soils in full sun. Each seedpod contains about 7 seeds, which can be ejected several feet away from the mother plant. Their stalks are numerous, erect, striated, and slightly pubescent. Dominant canopy trees in some of these habitats are either oaks (especially Black Oak) or pines. Individual plants can be short-lived or long-lived, depending on environmental conditions. The ravishing blossoms are borne atop erect stems, well above the elegant foliage of palmately compound blue-green leaves. 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. Family: Fabaceae Subfamily: Faboideae Tribe: Genisteae Subtribe: Lupininae Genus: Lupinus. It is estimated that it has declined in number by about 90% since 1900. Pods are yellow-grayish-brown, with straight lines, necklace-shaped, short and closely hirsute, easy shattered, with 5–6 seeds. Good air circulation helps combat powdery mildew. Reproduction is by seed and vegetative clones from the rhizomes. The blooming period occurs from late spring to early summer and lasts about 1 month for a colony of plants. Lupinus perennis (Wild Lupine) is a showy perennial boasting narrow, elongated clusters of usually deep blue, pea-like flowers from mid-spring to mid summer. The lateral edges of the banner fold backward from its center; as a flower ages, the center of the banner becomes more white. Lupinus perennis is used as foodplants by the caterpillars of several lepidoptera. Many places sell the seeds including Prairie Moon Nursery (not affiliated), and Outside Pride, but make sure you’re getting the native Lupinus perennis. Lupine is an excellent plant for dry sandy soils where so many … Plants appreciate some light afternoon shade in hot summer areas.

This decline has in turn been deemed one of the primary causes of the decline of the Karner blue butterfly. At the base of each flower, there is a linear-lanceolate floral bract that soon withers away.

Remaining habitat is often fragmented, which is problematic for the lupine because it limits the range over which it can reproduce. [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. Each compound leaf has a long ascending petiole about 1-4 inches long that is light green to reddish green. For other uses, see. Color: Blue Bloom Time: Late spring. [citation needed], Lupinus perennis is commonly mistaken for Lupinus polyphyllus (large-leaved lupine), which is commonly planted along roadsides. Flower. Floral bracts are styliform, shorter than the calyx, early falling.
