Creeping Water-primrose, Ludwigia peploides


Short description of Ludwigia peploides, Creeping Water-primrose

A creeping perennial water plant with long oval leaves like a willow and a large, bright yellow flower like that of a primrose. It can be separated from L. grandiflora by differences in chromosome number and morphology, most notably the petiolate glossy leaves, blunt stipules, smaller sepals (< 10 mm), and absence of pneumatophores (Armitage et al., 2013).

Description of Ludwigia peploides, Creeping Water-primrose status in GB

Ludwigia peploides is an invasive aquatic plant in southern France with the potential to become invasive Britain. There has been confusion between L. grandiflora and L. peploides in Britian in the past and all British records for L. peploides are now thought to to be misidentifications for Ludwigia grandiflora subsp. hexapetala which appears to be the only taxon that has escaped into the wild in the UK (Armitage et al., 2013).
