Ludwigia peploides. Creeping water-primrose is native to South America, Central America, parts of the southern United States, and possibly Australia. It is most likely that escape from aquaculture explains most of the adventive introductions; this plant is very commonly sold as an ornamental. Ecology of creeping macrophytes with special reference to Ludwigia peploides (H. B. K.) Raven. Due to the plant’s phenotypic plasticity, it could possibly be used in the reclamation of severely impacted ecosystems. As Australia's supply of freshwater is increasingly vulnerable to droughts, possibly as a result of climate change, there is an emphasis on water conservation and various regions have imposed restrictions on the use of water..

Additionally, the plant demonstrates a high degree of phenotypic plasticity, which allows it to adapt to a broad range of growing conditions and water regimes (Ruaux et al., 2009). Stems can be carried by animals to new locations, where new populations can establish and grow via vegetative expansion (Ruaux et al., 2009). The dense surface matting excludes the growth of native species, shades out submersed aquatic vegetation, and is inhospitable for fish and invertebrates. This plant can grow very densely, impeding navigation and interfering with hunting, fishing and other recreational activities (CEH, 2007). Description Water primrose is a perennial plant that stands erect along the shoreline but also forms long runners (up to 16 feet) that creep across wet soil or float out across the water surface.

As well as providing unsuitable habitat, it is also of little use as a food source; it contains saponins and calcium oxalate, which make it unpalatable to most herbivores. The Jepson Manual [online]. Leaves range from lance-shaped or willow-like (2 to inches long by 1/2 to 1 inch wide) on the erect stems to round or oval on the floating stems. nigrirostris and Lysathia flavipes have been reported to have L. peploides as their only host (Cordo and DeLoach, 1982); however, the use of non-native biological control agents can be a risky endeavour.

Read hotel reviews and choose the best hotel deal for your stay. The species possesses an allelopathic activity that has year-long effects on water quality and can lead to impoverished flora by decreasing seedling survival of vulnerable native taxa (Dandelot et al., 2008).

Pest status of harmful organisms in the Netherlands., Wageningen, Netherlands: Peconic Estuary Program, 2009. When invasive, this species causes declines in biodiversity (EPPO, 2004) through shading, competitive exclusion, and chemical allelopathic alteration of the growing environment. Online Database. L. peploides stems grow more horizontally and their petals are usually 1.0-1.5 cm long, and anthers are 1.0-1.7 mm, whereas L. grandiflora and L. hexapetala stems grow vertically and have larger petals and anthers.
