Description:

Lysimachia nummularia 'Aurea' is an attractive cultivar of L. nummularia. This plant is also known as Golden Creeping Jenny (the standard L. nummularia is commonly known as Creeping Jenny). The regular form, L. nummularia, can be found all over the U.S. both in its submersed and emersed forms. It is grown by most of the major nurseries, including Tropica, and is quite common in the trade. On a side note, this plant is also popularly used in terrestrial gardening.

L. nummularia 'Aurea', a moderately fast grower, is one of the most undemanding stem plants to grow. It can tolerate soft or hard water, pH in the 6.0-8.0 range, and temps from 15-25 C. Although this plant grows well in non-CO2, moderately lit aquaria, it prefers high light and CO2 addition along with plenty of NO3 and trace fertilization. Both L. nummularia and its 'Aurea' form are excellent indicator plants for NO3, showing very full, robust leaves with bright coloration only when its nitrate needs (>5 ppm) are met. Its growth is often stunted or slowed when these nutrients are deficient.

L. nummularia 'Aurea' tends to grow upward more than outward, producing few sideshoots. It readily breaks the surface of the water when it reaches the top of an aquarium. Pruning and propagation of Lysimachia nummularia 'Aurea' is very simple. Top and replant or simply top. This plant roots easily and often exhibits aerial roots.

This ovate leaved stem plant is best suited as a midground or background plant. Due to the light green, golden color, L. numularia 'Aurea' is a fine addition to many aquascapes as an accent, especially Dutch layouts in which the contrast of color, texture, and leaf size is critical.
