Lupine (Lupinus perennis) is an upright perennial wildflower with distinctive blue, purple, pink, or white flower spikes that bloom in late spring to early summer. As a nitrogen fixer, it enriches soil and attracts pollinators while tolerating poor, sandy soils.

Why grow it

Lupinus perennis outperforms many ornamental perennials in nitrogen fixation capacity, making it particularly valuable in polycultures where soil building matters. Compared to annual lupines, the perennial form provides reliable spring color across multiple seasons without reseeding, while its tolerance for infertile and sandy soils reduces establishment costs. It attracts native bees and other pollinators more consistently than many ornamental alternatives.

Watch out for

Lupine seed germination often benefits from scarification or cold stratification, so direct seeding may yield spotty results without preparation. In areas with consistent summer moisture, the plant can be short-lived or susceptible to root rot, making well-draining soil essential for longevity.
