Sv: Re: Java Fern
Got this from Tropica (www.tropica.dk (or is it www.tropica.com)). They
have three different types of java ferns, this is the most common:
Tropica No. 008
Part of the world South-East Asia
Height 20-35 cm
Width 12-18 cm
Light requirements low-high
Hardness tolerance average-hard
pH tolerance neutral
Microsorum pteropus is a water fern and is found attached to roots and
rocks in Nature. The olive green leaves grow from a horizontal rhizome. To
begin with the new plant should be attached to the substrate with a thin
wire or a rubberband until new anchor roots have been formed.
Microsorum pteropus does not require any special attension and surrives and
even grows at very low light intensities although at a lower growth rate.
It accepts very soft water and up to even brackish water. Microsorum
pteropus is easily reproduced from small adventitious plants which is
formed on the older leaves. This process is induced if the leaf floats at
the surface and the new plants grow bigger.
The black spots forming on the abaxial leaf side is not due to patogens as
often interpreted but rather sporangia needed in the sexual reproduction of
the plant. You can greatly enhance the application of this plant - try to
take a look at the article Plants cultivated on stones and tree roots!
Also, the article Microsorum pteropus 'WindelÝv' and Microsorum pteropus
'Tropica' provides more thorough information. See also fish-proof plants
from Tropica Aquarium Plants.
