Cryptocoryne Undulata is a striking plant that can be found in lowland ponds, and slow-moving waterways in Southeast Asia. They can be identified by their oblong leaves that are wavy, flat, and wide. From a distance, the leaves of the Cryptocoryne Undulata almost look like they have sharper edges than they actually do. In fact, the plant is named for the look of its leaves.

The leaves range in coloration from a darker green to a reddish hue in the home aquarium. You will most likely find this plant in its more brownish form in the wild. This is due to the nutrients and conditions of its environment.

Lighting Requirement

Cryptocoryne Undulata are not picky about its lighting requirements. This versatile plant can live and grow in most lighting levels. This makes them a great addition to the home aquarium as they are compatible with many species of fish. However, like all plants, there is a preferred lighting requirement. If they are kept at around medium intensity lighting, they will display more reddish coloration. In addition, too much bright lighting can slow down the growth of your Cryptocoryne Undulata, or hinder the plant from displaying its beautiful coloration.


Cryptocoryne Undulata can live in temperatures that range from 68F to 83F. This temperature range makes them a great addition to most home aquariums with many species of fish. Cryptocoryne Undulata are sensitive to shock, and this plant is not recommended to be uprooted and replanted. The shock from this process can cause damage to your plant, cause it to wilt, or cause the plant to rot and die. Thankfully, this plant is easy to propagate, and you can plant the trimmings in the substrate where you would like other Cryptocoryne Undulata plants to take root and grow.

Water pH

Cryptocoryne Undulata does require their water parameters to remain around 6.5 to 7.0 pH to grow and thrive. This makes them great for freshwater aquariums.

Cryptocoryne Undulata can grow up to 12 inches tall but can be trimmed to around half that height if desired. Cryptocoryne Undulata reach their maximum height at around 3 to 5 months of age, so you will not have to wait very long for your plant to grow into its beauty.

CO2 Requirement

Cryptocoryne Undulata plants do not require CO2 injections to grow and thrive. Like most plants, they benefit from some fertilization, but it is unnecessary.


It is fairly easy to propagate Cryptocoryne Undulata. Once your plant has matured, you will be able to see runners coming from close to the core of the plant. Just pick the runner that you wish to become its own plant, cut it, and plant it in your substrate.

Cryptocoryne Undulata Green

Cryptocoryne Undulata Green refers to the coloration of the plant’s leaves. You can get different colorations out of this plant depending on the conditions in which you are keeping it. You will get more greenish leaves if you keep your plant in lower-level lighting, and do not offer CO2 fertilizing to the plant.
