Tricyrtis perfoliata
Tricyrtis perfoliata is an endangered Japanese endemic toad lily that hails from the moist cliffs of the Nanuki River on Japan’s Kyushu Island. Tricyrtis perfoliata is one of several weeping toad lily species, but the only one that has up-facing open flowers (like Tricyrtis flava) instead of the bell-like flowers of Tricyrtis ishiana and Tricyrtis macrantha. The 2-3′ long, arching stem of Tricyrtis perfoliata passes through the ends (perfoliate) of the glossy green leaves. The stems are then laden with a stunning show of 1.5″ wide, axillary yellow flowers in late summer/early fall…truly stunning. Tricyrtis perfoliata is not a great specimen for regions with hot, dry summers.
