Overview

Cryptocoryne undulata Broad Leaves is one of the forgiving Sri Lankan crypts, in the same easy company as wendtii and beckettii. It is a rosette plant for the midground.

Did you know

The Broad Leaves and Red labels on shop shelves are the same Tropica plant under two catalog numbers. The pot ships as Broad Leaves under 110A. The tissue culture cup, long printed Cryptocoryne undulatus 'Red', is 110B and now carries the Broad Leaf name on Tropica's own page.

Caring for Cryptocoryne undulata Broad Leaves

Plant Cryptocoryne undulata Broad Leaves in a nutrient-rich substrate, with the crown just above the surface. Then let it settle. Like all crypts it can melt after planting or after a sharp change in water parameters, and it recovers from the roots.

Low light is enough, and it grows without added CO2. Its look shifts with conditions, and dim, lean tanks give taller plants in a greener brown. Strong light with CO2 gives shorter, more compact, reddish brown growth. It is a root feeder, so add root tabs if the substrate is not already rich. Keep the water at 72 to 82°F (22 to 28°C).

It grows at a moderate pace and spreads by runners. Cut a runner plant free once it has roots, or split an old clump at the rhizome.
