The illustrated growing guide
Wild Lupine
Lupinus perennis
Family Fabaceae
Est. zones 3-8

The ecologically vital native lupine — blue pea-flower spikes over sandy, lean, acid ground, fixing nitrogen and, most importantly, serving as the ONLY caterpillar host for the endangered Karner blue butterfly (plus frosted elfin and duskywing). This is the true tough native for dry sunny sites, not the short-lived flashy garden hybrids. Direct-sow it (it hates transplanting) and let it self-sow into a conservation-grade patch.
