Poisonous Plants, Pacific Northwest
The Lupine plant grows all over the BC coast in great numbers. The flower is a herbaceous perennial, up to 75 cm tall. Leaves are divided into 10 to 15 narrowly oblong leaflets. The leaflets are semi smooth above, and hairy beneath. Bonnet shaped flowers are born in racemes on a single center stalk that is up to 25 cm long. The flowers bloom in early to mid summer displaying their wide range of colors from deep blue, purple, light blue, lavender, rose, pink, yellow, and white.
The fruit is a pod about 2.5 cm long containing several somewhat flattened seeds. The seeds are cream colored and irregularly circular, and no more than 1 cm in diameter.
They thrive in dry open fields and woodland areas, you can see them along all the highways of the coastal region of BC in very thick patches. Lupine is poisonous to many animals. Poisoning varies depending on lupine species and varieties, and it is difficult to pin point to specific plant or animal since different animals become susceptible in different ways under varying range conditions.
Species and taxonomic differentiation’s between species are insufficiently characterized. Different lupines produce varying syndromes in a a given species of livestock.
