|synonyms_ref = {{citation needed|date=January 2014}} }} Nymphoides hydrophylla (crested floatingheart, white water snowflake, white snowflake{{citation needed|date=January 2014}}) is an aquatic plant of the family Menyanthaceae native to tropical Asia. It has cordate floating leaves that support a lax inflorescence of dainty white flowers with fringed petal margins. Its slim stem (spear) is edible, and is used as vegetable in Taiwan, mostly produced at Meinong District, Kaohsiung. Flowers of N. hydrophylla are gynodioecious.[1] The fruit is a capsule bearing many flattened seeds. The plants are commonly sold for use in ornamental water gardens. Outside their native range they can escape cultivation and become nuisance weeds, particularly in Florida. They are not killed by freezing, and have been reported in Lake Marion, South Carolina.[2] References1. ^{{cite journal |url=http://ejournal.sinica.edu.tw/bbas/content/1989/4/bot304-05.pdf |title=Seed coat micromorphology of Indian species of Nymphoides (Menyanthaceae) |author1=V.
