Silvery Lupine- Lupinus argenteus pursh
Silvery lupine begins growth in the early spring. By June, they are usually blooming and begin forming seeds in July into August. Silvery lupine grow in open grass lands, and are native to Wyoming and other areas in the West United States, along with few other countries. During wet summers, lupine populations can double then that of a dry spring and summer. The flower needs sun light enable to grow, but lupine thrives on moister.
Silvery lupine hare generally 50-100 centimeters tall. The flowers are nearly white with bluish shading, all different varying from light to dark. The flowers and in many slender clusters, 10-15 centimeters long while the leaves are lower on the stem, and have silky-hairy texture.
Silvery lupine contain toxic alkaloids, they are one of six species of lupine that are poisonous. The teratogenic alkaloid is highest in the seeds, pods, and young leaves. The toxins are found mostly in the seeds and pods. The younger the plant, the more toxic the plant is. The main animals that have been affected are included in the livestock category, especially sheep and cattle. Death is not a common result, because the organism would have to consume large amounts of the plants in a short time. However, birth defects have been extremely common in relation to the ingesting of lupine. Cases in human defects however have been less then animals, but non direct, such as women drinking goat’s milk during pregnancy, has shown to be the cause of some birth defects.
A large participant in the reproduction of these flowers is bees. The mutualism between bees and flowers allow bees to gather pollen, as well as flowers to reproduce and spread pollen. Bees are often attracted to lupine due to the simple pattern of which lupine flowers contain pollen. The top groups of flowers on the stem usually contain the most pollen that bees search for. Just by looking at the flowers, it is evident whether or not they have pollen, by tiny, dark spots in the flower. The perennial lupine flower is one of many native flowers to Wyoming, and one of the most common to see on hillsides and open grasslands.
