Scarlet Sterculia

For most of the year Sterculia lanceolata is a quiet, glossy-leaved evergreen of five to ten metres. In autumn it becomes something else entirely, as the fruit ripens into clusters of boat-shaped scarlet follicles that split open to display rows of shining black seeds against the red interior.
That display is the reason it is planted so widely as a park and street tree across southern China and Indochina, and it comes on a tree small enough to sit comfortably in a constrained urban space.
The Scarlet Sterculia is a compact evergreen street tree that delivers a genuinely unusual autumn display.
