Thermopsis rhombifolia var. divaricarpa, commonly known as Spreadfruit Goldenbanner, is a perennial herb native to the montane and subalpine zones of Western North America, including the Rocky Mountains and adjacent ranges. It is typically found in open woodlands, grasslands, and meadows, often in areas with calcareous soils. This species grows at a moderate rate to a height of 1.5-2.5 feet (0.46-0.76 meters) and a width of 1-1.5 feet (0.3-0.46 meters). It has a clumping form with trifoliate leaves and erect racemes of bright yellow, pea-like flowers that are quite showy and bloom in late spring to early summer. The flowers are followed by distinctive, elongated seed pods that spread outwards, giving the plant its common name.

Spreadfruit Goldenbanner is valued for its vibrant yellow flowers and its ability to adapt to a variety of soil conditions. It is often used in wildflower gardens, native plant landscapes, and for naturalizing in informal settings. It is drought-tolerant once established, making it suitable for xeriscaping. While it prefers full sun, it can tolerate part shade, especially in hotter climates. It thrives in medium draining soils, including clay, loam, or sandy types, and requires moderate watering. There are no major disease problems associated with this plant, but it can be susceptible to root rot if overwatered. It is not known to be invasive and does not have aggressive roots, making it a safe choice for gardeners looking to add native flora to their landscapes.CC BY-SA 4.0
