description
The fragrant water lily is a perennial herbaceous plant. This aquatic plant , which grows in water depths of more than 40 centimeters, usually forms branched rhizomes that are cylindrical and do not form bulbous, thickened side shoots. The petiole usually has no brown-red longitudinal stripes. The floating leaf blade is red or purple underneath and has pointed or acuminate basal lobes.
The hermaphroditic flowers are usually 7 to 15 (rarely up to 19) centimeters in diameter. The four sepals are green to reddish. There are mostly 23 to 32 (14 to 43) white, rarely pink, free petals present. The 35 to 120 stamens are yellow. The scar disc has 10 to 25 rays. The flowers are closed at night. The flowering period extends from June to August.
