Sagittaria — 7 species

Sagittaria is a genus of aquatic plants with distinctively arrow-shaped emergent leaves and three-petalled white flowers, ranging from the compact Sagittaria subulata to the robust Sagittaria latifolia and Sagittaria sagittifolia. They thrive in full sun to partial shade with permanently wet or submerged roots — pond margins, shallow water, or waterlogged containers are ideal. Pet safety varies across the genus: Sagittaria latifolia is generally considered non-toxic to cats and dogs, but data on all species is limited, so confirm toxicity for each species before buying.
