Cryptocoryne undulata ‘Broad Leaf’

Aquarium plant from tissue culture in closed cup.

This red version of Cryptocoryne undulata grows wild in rivers of Sri Lanka.

It is an easy plant, tolerant of very different conditions in an aquarium. Appearance of the plant will partially depend on these conditions.

Low levels of light and nutrients will produce a relatively tall, greenish-brown plant of slow growth. Higher levels of light and nutrition, combined with added CO2, will make the plant grow considerably faster producing shorter leaves of a reddish-brown colour.
