Nymphaea — 27 species

Nymphaea are the classic aquatic water lilies, floating their broad pads and showy flowers — white, yellow, pink, or purple — across ponds and water features worldwide. They need at least six hours of direct sun daily and are grown with their crowns submerged in heavy aquatic soil, making them the defining plants of ornamental water gardens. Pet safety varies across the genus: some species are considered non-toxic while others may cause mild gastrointestinal irritation if ingested. Always verify the specific cultivar before adding Nymphaea to a garden shared with cats or dogs.
