Lupinus perennis

Sundial Lupine (Lupinus perennis) is a perennial wildflower native to eastern North America, known for its striking spikes of blue to violet pea-like flowers that bloom in late spring to early summer. This plant typically grows 1 to 2 feet tall and features palmately compound leaves, giving it a distinctive, airy appearance. Sundial Lupine thrives in well-drained, sandy or loamy soils and prefers full sun, though it can tolerate light shade. It is drought-tolerant once established and requires only moderate watering, making it well-suited for prairie gardens and naturalized landscapes. This species is an important host plant for the endangered Karner Blue butterfly and supports a variety of pollinators.
