Fritillaria japonica is a perennial herb that inhabits deciduous forests or their edges in mountainous regions. Stems grow to 10-30cm in height, and leaves are opposite at lower parts and in whorls of three at upper parts - blades are lanceolate to broadly lanceolate, 2.5-10cm in length. Stem tops bear single flower buds and bloom facing downwards; perianth lobes, with many purple-brown dots, are long-oblong-shaped, 15-25cm in diameter, bend at the nectary positions towards the inside, and the tips are pointed. Anthers are white. Bloom time: March-April.
