Willow Hygro
Hygrophila angustifolia
General information: It is variable in leaf shape and colour from various locations around the NT. There is a broader leaf light green version on the Howard River floodplain billabongs. Within the Howard River there is a red/brown thin leaf version. The form cultured at Aquagreen is red in bright light and comes from a roadside drain on the Adelaide River Floodplain.
Cultivation notes : It is an easy to cultivate plant when the basics are kept under control. It likes a rich substrate and generally occurs where there are more fertile soils. In the aquarium it likes bright light and does much better with CO2 fertilisation and pH control. It is best used as background plant as it grows tall and quite quickly when the water quality is suitable for plants.
Distribution : New Guinea and within Australia it occurs in NT, WA, Qld and Northern NSW.
Selling details : sold by bunch of cut stems tied at the base.
