distribution_en:

description_en: Genus of 20 species of marginal and submerged, herbaceous aquatic perennials and annuals, found mainly on muddy banks or in shallow water in temperate and tropical Europe, Asia, and North, Central, and South America. The often decorative leaves are aerial, floating, or submerged, and linear to elliptic, lance-shaped, ovate, or arrow-shaped. Panicles or racemes of whorled, 3-petalled, saucer-shaped white flowers are borne in summer. Most are excellent for the margins of a wildlife pool, where their tuberous rootstocks may spread; some (including S. latifolia and S. sagittifolia) produce walnut-sized tubers that attract waterfowl. Grow S. subulata in an aquarium for its attractive submerged leaves. In frost-prone areas, grow tender species in a pool in a cool or temperate greenhouse.

hardiness_en: Fully hardy to frost tender.

cultivation_en:

propagation_en: Sow seed as soon as ripe in containers standing in trays of shallow water. Remove runners, or collect and plant overwintering tubers, in spring.

pests_en: Leaves may be damaged by water-lily aphid.
