Ludwigia peruensis is endemic to many tropical regions, in particular Asia, Africa, and South America.

In the wild, it can be found in areas such as ponds, rivers, and streams with a soft, sandy substrate.

It can tolerate temperatures of up to 78°F but does prefer temperatures that remain between 68°F and 78°F.

pH Preference

Ludwigia peruensis prefers a pH that remains between 6.5 and 7.5. The best way to achieve this is to use a tool such as an aquarium water test kit, to make sure the aquarium is properly maintained.

Also, this plant is tolerant to moderately hard water, but it is important to not allow it to become too hardened.

Vivarium Type

Ludwigia Glandulosa is quite an easy-going species. With that in mind, it will not be too complicated when it comes to choosing the type of enclosure it is grown in. It is best to try and replicate the plant’s natural habitat as much as possible.

Doing so will make it easier to provide this foliage plant with its basic needs. The proper setup and theme of the enclosure will make a big difference to the overall look and health of the plant. Be sure to choose setups that are moist and high in humidity.

Here are recommended vivariums it will do well in:

  • Paludariums – Half aquatic/ half terrain-based enclosure.
  • Ripariums – Mostly aquatic-based enclosures with some terrain features present.
  • Aquariums – Fully aquatic-based enclosure with little to no dry terrain.

Vivarium Placement

Ludwigia peruensis is usually placed in the middle or at the back of an aquarium.

It is important to make sure it is not in an area of the tank that has too much direct sunlight, as the leaves may burn and cause the plant to die.

This species of Ludwigia can thrive fully submerged in the water.


Ludwigia peruensis does best in a substrate that has been made from sand or soil.

It is important that the aquatic substrate is not too thick or too loose, as it will not be able to properly absorb nutrients from the water.

If possible, it is also best to avoid using substrates with added fertilizers, as this can potentially cause an imbalance in the water chemistry.


Ludwigia peruensis prefers moderate to bright aquatic lighting while avoiding direct sunlight.

Lighting must also remain consistent, with no drastic changes in exposure, as this can cause the plant to become stressed and die. Recommended bulbs range from 6500K to 10,000K.
