Perennial herbs (grow for several years from their same root system) found at forest edges and in forests in mountains. Flower stems (only bloom flowers without any leaves) grow at the tips of stems or from petioles and bloom some flowers facing upward. Flowers are 3 cm in diameter and have purple spots on white petals. This spots resemble the pattern of the chest of lesser cuckoo, hence the Japanese name Yama-hototogisu literally meaning lesser cuckoo in mountains. Six petals curled downward and stamens and pistils protrude like fountains. Leaves are 8 to 13 cm oval-shaped with pointed tip but curl stems at the base. Stems have hair facing downward but amount of hair vary to each plant. After flowering, bear 3 cm long fruits. Split from the upper side and pop small oval-shaped seeds when ripen.
