One of tropical East Africa's most beautiful flowering trees, the siala boasts erect clusters of trumpet-shaped golden yellow flowers. This fairly fast-growing deciduous tree grows on forest edges and along river banks. It develops a slender, upright trunk and distinctive oblong canopy that doesn't cast a broad shadow. The trunk may also slightly curve and displays grayish sienna bark that flakes away in strips.The compound leaves are rich bright green and comprise 7 to 11 leaflets with deep veins. If soil isn't overly fertile, foliage is more yellow-green. Usually deciduous, flowering occurs during the warm months any time of year when soil moisture and leaves are present.
