They are a perennial plant that grows at such sunny and arid places as in the pool of the forests in the mountain area and the grasslands (Perennial plant takes several years to grow). As the color of the flower is compared to the firefly luminescence, they are named. During the season of new green leaves, flowers tinged with vivid blue-purple color stand out like floating from others. The flower is about 1.5 to 2 cm in diameter, and few of them bloom in cluster at the root of the leaf at the upper part of a thin stalk. The flower petal is split into 5 with the center part white striped like being arched. The leaf is thin and long shoehorn-shaped about 2 to 6 cm long. The leaves and stems bear hard trichome and rough to touch them. When the flowers wither, they grow long branches ‘stolons’ (Stolon: Sousyutsushi is the branch creeping on the ground to extend, also called ‘Runner’), and furthermore they let the roots out from the top of the stolon branches to cultivate a new stub. The leaves remain still on even in the winter.
