Variableleaf water hyacinth

Pontederia diversifolia is a beautiful stem plant from tropical Central and South America. This aquatic lives in shallow waters or on muddy substrates. Sometimes it is also encountered in the natural habitats with the strong current where it developes long, up to 10cm, leaves arranged in a distinct spiral along the stem. After reaching the water surface, the stem tip develops round, reniform, shining floating leaves and nice blue flowers. In the aquarium planted in the background or midground it will have the major effect.

It is native to Colombia and present in Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Nicaragua, Panamá, Suriname, and Venezuela. Afterwards, it was also introduced into Cuba, Dominican Republic, India, Puerto Rico, and Taiwan.

Synonym: Eichhornia diversifolia.

For the better growth Pontederia diversifolia should be well supplied with nutrients and CO2.

Plant care

Pontederia diversifolia grows submersed or with floating leaves in tropical regions. It is known to form vast zones of floating leaves in rivers.  This fast grower should be trimmed in time to prevent floating leaves, if these are undesirable. It should never be planted in shady areas, as its leaves will change their colour and tirn transparent.

Water care

Pontederia diversifolia does well in water with slightly acid to neutral pH value. Sufficient nitrate and phosphate are crucial to its health, too – approx. 5-20 mg/l of nitrate and 1-2 mg/l of phosphate. A lack of nitrate, phosphate and iron are probably the reason for difficulties in cultivating this plant.
