Lysimachia nummularia aurea is the golden form of creeping Jenny, producing rounded, coin-shaped leaves in warm yellow-green to golden tones that provide a striking colour contrast in the midground of planted layouts. Its creeping, trailing growth habit fills gaps and spreads gently across the substrate, creating a softly textured golden accent among green and red neighbouring plants.It is an undemanding species growing well under medium light without CO2 injection. The golden colouration is most vivid under good light; in lower light conditions the leaves may become more green. Regular trimming of upward-growing stems keeps it in the creeping form typical of the species. Cuttings root readily for propagation.Supplied as an established potted plant, Lysimachia nummularia aurea suits aquariums from 40 litres upward. Its golden leaf colour, easy care, and creeping habit make it one of the more distinctive and versatile midground options for planted aquariums where a warm colour accent at low height is needed.
