Crypt wendtii plants are available in a variety of colors, from green to bronze. It is a great plant for beginners because it can grow in a range of lighting conditions and is forgiving when it comes to fertilizers. Baby plants can be removed from runners once they grow a few leaves.
To understand this plant better, their native habit is mostly comprised of slow flowing streams and rivers in lowland forests. These are often seasonally inundated forest pools or river banks that are submerged only during the wet seasons of the year. Cryptocoryne are sensitive to environmental conditions. Drastic shifts will often result in a phenomenon referred to as crypt melt where the plant loses all its leaves. This can be triggered when converting a emersed grown plant to submersed planting in an aquarium.When shopping for crypts, consider that many at retails channels source plants from nurseries that grow emersed. Another theory is that excessive nitrates may erode and trigger leaf melting so regular water changes are encouraged.
Red and Bronze wendtii are often confused. Red has visible veining in the leaf and bronze is a solid leaf color; otherwise, they are almost identical visually.

Tips on growing them them for scape purposes, use medium to high full spectrum light. I have found this encourages shorter, wider leaf growth with far richer color. See below.
