About Riverbank Lupine: This wildflower was first found near the Columbia River and described in 1828 by Scotsman David Douglas, the first botanist to methodically find and classify over 250 plants in the northwestern region of the United States.The name Lupine comes from the Latin “lupus,” meaning wolf. This refers to the folk belief that this plant took nutrients from the soil. Ironically, this plant actually improves the soil because of its nitrogen fixing abilities.
Riverbank Lupine Germination: To soften the hard coating on these seeds, rub them lightly with sandpaper or soak them in 180 degrees F water overnight before sowing. Sow them in early spring, planting 1/2” deep. Keep the soil lightly moist until germination.
Growing Riverbank Lupine Seeds: These seedlings grow very slowly and are rather fragile. Water them occasionally and protect from freezing temperatures. Though mature plants tolerate drought conditions well, provide water occasionally in very dry weather. This plant can be poisonous to livestock if present in excessive amounts. These plants resent having their roots disturbed.
Harvesting Riverbank Lupine: For cut flowers, choose stems with flowers that have just opened. Strip the foliage that will fall below the water level, and place in water immediately.
Saving Riverbank Lupine Seeds: As the seed pods develop, watch them carefully. As soon as they ripen fully they will split and drop their seed. When the pods begin to turn brown, remove them and spread them out to dry. Remove the seed from the pods and store it in a cool, dry place. Keep in mind that these seeds are highly poisonous.
