Hemerocallis vespertina,
a perennial herb found in grasslands in mountainous regions, emerges
leaves in two rows at the bases, each linear, 40-60cm long, 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 like moths. Bloom
time: July-September.
