In late spring to early summer, ravishing conical panicles of 10-20 trumpet-shaped, white flowers, 1.5 in. across (4 cm), with abundant yellow stripes and purple speckles on their throats, bloom dramatically above the leaves.

Very adaptable to adverse conditions, 'Aurea' makes a grand statement in the landscape and serves as an ornamental shade or street tree.
