Hansen's Nardoo

Marsilea hirsuta

General information : It is a very small Marselia that grows submerged in lower to medium light situations. The leaves are much smaller when grown submerse and in lower light situations the leaves become single lobed as in the fourth photo.

Cultivation notes : No substrate or water quality details are available from the collection place. It grows well in medium to high light but tends to produce small leaves. In the lower light situations it produces bigger leaves with a single lobe, very different from the emerse plant. At Aquagreen it is cultivated in 70% shaded natural light. pH about 7, GH 50 ppm, KH 60 ppm with the pH controlled to 7 with carbon dioxide. Grown in a 60cm deep aquarium medium to low light produces runners with single lobe on leaves.

Distribution : All mainland states of Australia.

Selling details : Sold in a lot of 50 plantlets washed free of substrate.
