Golden Beans is a hardy perennial that welcomes spring with spikes of bright yellow, pea-like flowers rising above deep green, rhombus-shaped leaves. This tough native is an early-season favorite for pollinators, with lightly fragrant blooms, especially noticeable on warm spring days. It attracts bees and other pollinators with its nectar-rich flowers, while seeds may be eaten by birds or small mammals, though it is not a major wildlife food source. Its deep taproot makes it highly drought-tolerant, and as a nitrogen fixer, it helps improve soil health over time.

Well-suited to prairie plantings, dry meadows, sunny slopes, and restoration projects, Golden Beans is a standout choice for naturalized landscapes. Its bright yellow spring blooms and drought tolerance make it ideal for xeriscapes and low-maintenance rural or larger urban gardens. Moderately deer-resistant due to its tough, bitter foliage, though occasional browsing may occur.
