Description
Ludwigia Peploides, also known as water primrose or creeping primrose-willow, is a perennial aquatic plant that is native to South America. It is considered an invasive species in many parts of the world, including the United States, due to its rapid growth and ability to outcompete native plants.The plant has a prostrate growth habit and can form dense mats on the surface of the water, which can cause harm to aquatic ecosystems by blocking sunlight and reducing oxygen levels. Ludwigia Peploides is also difficult to control once established, as it can regenerate from stem fragments and seeds.
