distribution_en:
description_en: Genus of 80-100 species of marginal to deep-water aquatic perennials, distributed almost throughout the world, flourishing in freshwater ditches, ponds, canals, and waterways. They are cultivated as oxygenators in water gardens and for their decorative effect in aquariums. The branched, creeping rhizomes spread rapidly in muddy pool bottoms, where they support an inter-woven, mat-like network of translucent, linear to lance-shaped submerged leaves, and leathery, opaque, lance-shaped to rounded floating leaves. Inconspicuous flowers are borne in fleshy spikes just above the water. Grow the hardy species as oxygenators in outdoor pools; P. crispus tolerates polluted water better than any other oxygenator, and can also be used in cold-water aquariums. In frost-prone climates, grow tender species in cool-water aquariums; in warmer climates, they are suitable for outdoor pools.
hardiness_en: Fully hardy to frost tender.
