This plant displays narrow pointed leaves that are pink to red or reddish purple in colour depending on conditions. It grows straight with side shoots rarely forming unless stems are topped. Ludwigia Glandulosa does not grow particularly fast, making it a perfect midground focal point.
This plant is somewhat difficult to grow, requiring intense light to retain colouration and to stop leaves from being dropped. Regular fertilisation is also required, with CO2 recommended for best growth and colouration.
Ludwigia glandulosa, a native of the U.S., is distributed through out most of the southern states where it grows in wetland areas as well as roadside ditches. Despite its wide range, it is classified as a threatened and endangered species in Indiana and Maryland, respectively.
L. glandulosa is moderately difficult to grow. Without high light, its leaves will turn green and will fall off. Even in high light tanks, lower leaves are still susceptible to dropping. Being such a high light plant, regular dosing of trace and iron become necessary. Other than these needs, this plant isn�t very challenging. It isn't very picky about nitrate and phosphate levels as long as these macronutrients are present in some amount. Successful growth has been demonstrated with NO3 ranging from 5-25 ppm and PO4 of 0.5-3 ppm. Unlike typical 'red' plants, L. glandulosa does not need to have low nitrate levels to maintain its red coloration.
Unlike other Ludwigias, L. glandulosa does not like to branch. Even when this plant grows right up to the water line, it tends not to branch, but rather grows out of the water. To force side shoot growth, one usually has to snip the tip of the stem.
Because of the intense coloration of this plant, L. glandulosa is ideal as a focal point plant. Its intense red/purple leaves will easily attract the eye. Because this plant is not extremely fast-growing and does not often branch, one can easily use this plant in the Dutch-style plant streets.
