Ludwigia glandulosa is a captivating aquatic plant native to the southeastern United States, with its range extending north to Illinois and Indiana. It thrives in wetlands and even roadside ditches, yet despite its widespread distribution, it is classified as endangered or critically endangered in Louisiana. In the aquarium trade, it is often mistakenly labeled as Ludwigia peruensis. This species features lanceolate, alternate leaves with a deep reddish-purple hue that makes it a highly desirable choice for aquascaping.
When grown submerged, L. glandulosa maintains a strictly upright growth pattern with minimal branching, while its emersed form produces creeping runners and ramified shoots that can reach up to 31 inches in height. This plant requires high-intensity lighting to maintain its vibrant coloration and avoid leaf loss, as inadequate light causes its foliage to turn green before being shed. In addition to strong lighting, a consistent supply of micronutrients, particularly iron, is essential for healthy growth. While it does not demand excessive levels of macronutrients, maintaining nitrate levels between 5–25 mg/L and phosphate levels between 0.1–3 mg/L ensures optimal development.
Due to its rigid, upright growth, L. glandulosa seldom produces lateral shoots unless the central stem is trimmed, encouraging a more bushy appearance. Its intense red coloration makes it an exceptional focal point in aquascapes, particularly in Dutch-style planted tanks, where it can be used to create striking plant streets. With its slow growth rate and bold presence, Ludwigia glandulosa is an excellent choice for aquarists seeking a unique and visually stunning addition to their aquarium.
