About

Barclaya is a genus of eight species of flowering plants of the family Nymphaeaceae. Barclaya are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay.

How to grow it

Barclaya longifolia is a popular aquarium plant. Under high light conditions the attractive, upright foliage displays green colouration. Under lower light conditions brownish foliage is produced. It easily sets seed in cultivation, if pollen is deposited on the stigma.

Where it grows

Within tropical rainforests, Barclaya develops alongside streams or at their fringes. The escalating deforestation across Southeast Asia is causing the habitats to become clouded, endangering Barclaya.
