Ludwigia glandulosa
This plant was originally introduced to the hobby under the erroneous name, L. perennis (or sometimes L. peruensis) It is one of the more difficult aquarium plants and must have high light, strong supplemental CO2 and good nutrition. Even under these conditions, it is not a fast grower submersed and will sometime fail for no discernible reason. Never the less, it is such a beautiful plant that many hobbyists enjoy trying their hand at it!
