About plant names...
Yellow bush lupines are native to western North America. Like other members of
the extensive pea family, these lupines and their symbiotic bacteria trap atmospheric
nitrogen, converting it to a form that provides the plant with necessary nutrients.
Hence lupines can grow in areas, like sand dunes, that are too deficient in nitrogen to support other
plants. A bright yellow dye can be extracted from the flowers. Outside of their native
habitat, yellow bush lupines are now considered to be invasives.
Identification: These lupines can reach 5-6½′ (1.5-2 m) in height, and about 4′ (1.2 m) around,
significantly larger than other lupine species. They produce deep roots which help to stabilize coastal sandy
areas. Leaves are silky, dark green or gray-green, palm-like in appearance, with
5-12 leaflets on each leaf. Each leaflet is ¾-2″ (2-6 cm) long. Flowers occur in spikes 6″ (15 cm) long. They
have a sweet scent. Usually yellow, they may be lilac or blue instead.
