Hemerocallis vespertina, a
perennial herb found in grasslands of mountainous regions, emerges
with leaves arranged in two rows at the base, each linear, 40-60cm
long and 5-15mm wide. Flower stalks measure 1-1.5m in height; the
inflorescences branch in two parts; flowers bloom from one to
another in the evening and fade in the morning the next day. The perianths are light yellow, visible to night-flying insects, such as
moths. Bloom time: July-September.
