Heliconia rostrata
Unmistakable and architectural, the heliconia hangs its flower in a long chain of waxy claws, scarlet-tipped with yellow and green, like a string of painted lobster pincers. The true flowers hide inside these bracts, offering nectar to hummingbirds. It thrives in the warm damp of the interior, and a stand of it beside a forest waterfall is pure theatre.
