canaliculatum is a perennial plant in shallow water like
paddies or ponds; its rhizomes are short, with many fibrous
roots. Radical leaves have 20-50cm-long petioles; blades
measure 5-17cm long, 3-7cm wide, in the shape of an oval to
oval-like oblong. Scapes grow to 0.5-1.2m in height and make
themselves be in whorls of 3-4 branches, and the branches do
the same again and again. And, small white flowers make
themselves bloom on those branch ends. The flowers, 7-8mm
across, bloom in the mornings and wither within the days.
Bloom time: June-October.
