Cultivation
The yellow-flowering form is widely grown as an ornamental plant for its attractive yellow flowers and also to bind drifting sand dunes. It has however escaped from cultivation to become an invasive species in many areas. Outside of its native range in North America, it is somewhat invasive both in southern California, and further north to southwestern Canada. It has also been introduced in western Europe, Australia (where it is considered a potential noxious weed), New Zealand, Anatolia Aegean Region of Turkey and southern South America, including the Falkland Islands.
Like many members of the family Fabaceae, it is an effective fixer of nitrogen in the soil. Where it has been introduced, it changes the chemistry of the soil, and therefore allows other exotics to establish themselves, to the detriment of native vegetation adapted to low nitrogen levels. It also hybridizes with other lupine species such as Lupinus littoralis (seashore lupin) and Lupinus rivularis (riverbank lupin), further endangering the survival of those forms.

Famous quotes containing the word cultivation:
“If you will think about what you ought to do for other people, your character will take care of itself. Character is a by-product, and any man who devotes himself to its cultivation in his own case will become a selfish prig.”
—Woodrow Wilson (1856–1924)
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
“We are on a mission: we are called to the cultivation of the earth.”
—Novalis [Friedrich Von Hardenberg] (1772–1801)
