The goldenrain is an up to 15 m tall deciduous tree with a broad and expansive crown.

The large leaves grow alternately on the branch. They generally consist of 7-15 leaflets that finish with a single terminal leaflet (unequally pinnate). The leaflets are irregularly coarsely serrated to deeply lobed.

It can grow as a tree or shrub and generally has an erect stem with a very broad crown. The bark is grey-brown with vertical fissures.

The flowers are yellow with an orange base. They grow in large upright much-branched panicles.

The fruits are dry-skinned capsules with a papery bladder-shaped covering. The seeds are pea-sized and dark-brown.
