The flower of Nymphaea alba, a species of water lily Bud of Nelumbo nucifera, an aquatic plant.. Aquatic plants also referred to as hydrophytes [1] are vascular plants and non-vascular plants [2] that have adapted to live in aquatic environments (saltwater or freshwater).
Another unique feature of cell walls of seagrasses is the occurrence of unusual pectic polysaccharides called apiogalacturonans. [104] [105] [11] In addition to polysaccharides, glycoproteins of the hydroxyproline-rich glycoprotein family, [106] are important components of cell walls of land plants.
It is also the birth flower for the month of July.

Hobbyists use aquatic plants for aquascaping, of several aesthetic styles. Most of these plant species are found either partially or fully submerged in their natural habitat. Although there are a handful of obligate aquatic plants that must be grown entirely underwater, most can grow fully emersed if the soil is moist.
The underwater leaves of this species have a handsome appearance that is appreciated by aquarists who often remove the floating leaves to keep it as a fully subaquatic plant. [5] The flowers are quite large, about 15 cm in diameter when fully open. They tend to close during the daytime and open wide at night.
