Lysimachia nummularia 'Aurea'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

To achieve its signature golden hue, it must be placed in a high-light area, typically in the midground or foreground. If shaded, it will revert to a standard green color. It is excellent for providing a striking pop of yellow amidst darker green and red plants.

Botanical form

Stem

It shares the same round, coin-like leaves as the standard variety, but its foliage is a stunning, bright golden-yellow. The stems trail and creep along the substrate or hardscape, rooting at the nodes. Its unique coloration makes it a standout specimen in any planted tank.

Growth

Medium

Its growth rate is moderate to fast, though typically slightly slower than the standard green variety. High light and CO2 injection will significantly speed up its growth. Regular maintenance is required to keep it from sprawling out of its designated area.

Substrate

Medium

Lysimachia nummularia 'Aurea' is a bright yellow variant that forms an excellent root system in a variety of substrates, including plain sand or gravel. Planting in about 2 inches of substrate ensures its stems stay put in moderate water flow. To achieve the brightest golden-yellow foliage, incorporating root tabs or using a nutrient-rich base will significantly boost its trace element uptake.

Column fertilization

Recommended

Regular dosing of liquid fertilizers is important to sustain its bright coloration and vigorous growth. A comprehensive fertilizer containing trace elements and iron is recommended. Lean water conditions may result in slower growth and less vibrant colors.

Root fertilization

Recommended

While it can grow in basic substrates, an active soil or root tabs will significantly enhance its growth and color. It benefits from a strong root system to absorb nutrients effectively. A rich substrate helps it bounce back quickly after trimming.

Trimming

Occasional

Trim by cutting the trailing stems to maintain its shape or to encourage a more compact, bushy form. The cuttings can be easily replanted to create a larger golden patch. Trimming also prevents it from creeping over and shading smaller foreground plants.

Propagation

Cuttings

Propagation is very easy through stem cuttings. Simply snip a section of the stem and plant it in the substrate. Roots will quickly form at the nodes, establishing a new plant.

Sensitivity

Moderate

This golden variety is sensitive to low light, which causes it to lose its unique color and turn green. It is generally hardy but appreciates clean, well-oxygenated water. It can tolerate cooler temperatures, making it suitable for unheated tanks.

Layout role

Midground, Background

It is highly valued for its rare bright yellow-gold color, which acts as a powerful focal point or accent. It contrasts beautifully with dark green mosses, deep red stem plants, and dark hardscape. It is often used to brighten up specific areas of the aquascape.
