sundial lupine
Quick Summary
The sundial lupine (Lupinus perennis) is a species of herbaceous plant belonging to the genus Lupinus, which is part of the pea family (Fabaceae). This genus, named after the Latin word for "wolf," was once mistakenly thought to deplete soil minerals, but in reality, lupines enrich the soil by fixing nitrogen.1
Sundial lupines are found in dry, open woods and fields across eastern North America and are characterized by their blue flower spikes. While many lupine species are cultivated for ornamental purposes, forage, or as cover crops, the sundial lupine is primarily noted for its native habitat and attractive blue flowers.12
