Cryptocoryne undulatus ‘Red’ TROPICA 1-2-GROW!

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.

Cryptocoryne undulatus ‘Red’ (Tropica 1-2-Grow!) in Singapore

This red form of Cryptocoryne undulata comes to you as clean tissue-culture plantlets, ready to add warm tone and that signature wavy-edged leaf to your midground. Native to Sri Lankan rivers, it is genuinely easy and forgiving, tolerating a broad spread of aquarium conditions. We find its final look depends heavily on your setup, which makes it a satisfying plant to experiment with as your tank matures.

Under lower light and leaner feeding it grows taller and greener-brown with slower pace; brighter light and richer nutrients pull out the reddish colour and a more compact form. For Singapore hobbyists that flexibility is handy, since it adapts to a simple low-tech tank or a higher-energy planted layout alike. Our warm 27-29C water needs no chiller, and a nutritious substrate with root tabs deepens the red over time.
