Crotalaria agatiflora subsp. imperialis, commonly known as Canarybird-Bush, is an evergreen shrub native to the open woodlands and grasslands of Eastern Africa. It typically grows to a height and width of 8-12 feet (2.4-3.7 meters), presenting a rounded, bushy form. The Canarybird-Bush is notable for its unique inflorescences, which consist of large, pendulous, pea-like flowers that are yellow with a greenish hue, blooming profusely in the spring, summer, and fall. The flowers are quite showy and attract pollinators, adding to the plant’s ornamental value.

Canarybird-Bush is valued for its vibrant, year-round foliage and distinctive flowers, which make it a striking addition to tropical and subtropical gardens. It is used in cultivation for border planting, as a specimen plant, or for creating informal hedges. This shrub prefers full sun to part shade and requires medium to high amounts of water, thriving in well-drained soils. While it is generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is not known to have aggressive roots or significant disease problems, but gardeners should be aware of its potential to spread if conditions are favorable.CC BY-SA 4.0
