Ludwigia Glandulosa TC – IC013

Ludwigia glandulosa is one of the prettiest colorful aquarium plants, but it is also one of the most difficult to care for. It develops superb wine-red leaves under favourable conditions – strong lighting, good CO₂ supply, nutrient-rich substrate, temperatures not permanently above 25 °C. This Ludwigia species is found in southeastern North American marshes. In trade, it is frequently mislabeled as “Ludwigia perennis” or “Ludwigia peruensis.”

It looks best in the midground as a standalone clump of stems of various lengths. It has erect, slightly branching, strong submerged stems that are densely set with small, lanceolate leaves, unlike other Ludwigias. Ludwigia glandulosa is an excellent accent plant because of its vivid hue.

Ludwigia glandulosa (ssp. glandulosa and ssp. brachycarpa), a cylindric-fruited primrose willow, is widespread in most of the southeastern United States. To the north, it has a distribution region that includes Illinois and Indiana. Wetland areas are preferred, but wet road ditches are also ok. 

In Indiana and Louisiana, despite its widespread distribution, it is classified as endangered or severely endangered.

It is commonly sold under the incorrect name “Ludwigia perennis,” which is the name of another species found in Asia, Africa, and Australia and is not a synonym for L. glandulosa. It’s also known as “Ludwigia peruensis,” which is clearly derived from the word “perennis.”

Care Tips

• The plant requires constant CO₂ infusion
• Lighting provision is from moderate to high
