In Malaysia, most of these aquatic flowering plants are found in ponds, ditches, lakes, dams, rivers, irrigation canals and wet paddy fields. Due to their rapid growth , ability to constantly regenerate and their tolerance to a wide range of environmental conditions, some are considered weeds.

More than 15 species of these plants are edible. Some species are harvested and used as animal fodder. Paddy farmers increase their crop yield by using these plants as green manure in their fields.

Some have medicinal value, while certain species are used as ornaments and a source of oxygen in fish tanks and aquariums. Some are cultivated as ornaments in ponds while others are used to make handicrafts.

Recently, efforts have been made to rediscover the usefulness of these plants. In the past, these plants were also depicted as motifs in ancients architecture, art, woodwork, as well as on fabrics and tapestries.

These days, most of the species which require clean water to flourish are being rediscovered for other beneficial uses. They are being preserved and utilised as food for other aquatic life, grown as ornamental and aquarium plants for the horticulture and landscaping business as well as raw materials for the cottage industry.
