Lysimachia nummularia 'Aurea' (Golden Creeping Jenny) care

Light

Lysimachia nummularia 'Aurea' wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. Full sun to partial shade. Bright light brings out the strongest golden colour; deep shade turns leaves lime-green, while harsh, dry full sun can scorch them. Morning sun with afternoon shade is ideal. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water lysimachia nummularia 'aurea' keep consistently moist; water whenever the surface starts to dry. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Like the species it demands damp soil and tolerates pond margins. The golden foliage scorches faster than green forms if roots dry out in strong sun, so reliable moisture is essential for clean colour.

Soil and pot

Lysimachia nummularia 'Aurea' grows best in moist, fertile, humus-rich loam. Any moisture-retentive soil suits it, from damp border loam to boggy clay and pond-edge mud. Enrich thin soils with compost to keep the foliage dense and well-coloured. Tolerant of a broad pH range. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Lysimachia nummularia 'Aurea' sits happiest at around 50-90% humidity and 5-26°C (41-79°F). A hardy outdoor plant indifferent to air humidity; consistent soil moisture is what keeps the bright leaves turgid and unscorched. It thrives in the humid microclimate beside water. If you keep the room above 5 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed lysimachia nummularia 'aurea' sparingly. Modest feeding only. Rich soil already drives vigorous spread, so a spring compost topdressing usually suffices. For containers, a half-strength balanced liquid feed monthly in summer keeps the gold foliage lush. Avoid high-nitrogen feeds, which can mute leaf colour. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on lysimachia nummularia 'aurea' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Loss of gold colour — In too much shade the leaves revert toward plain green. Give it brighter (but not scorching) light to keep the chartreuse-gold tones.
• Leaf scorch — Golden foliage burns more readily than green forms when roots are dry in strong sun. Keep soil moist and shelter from blistering afternoon sun in hot regions.
• Invasive spread — Just as vigorous as the green species and can overrun neighbours or escape gardens. Site it where it can be contained or grow in containers.
• Thin, woody centres — Mature mats can go bare in the middle. Shear back tired growth to stimulate fresh, well-coloured rooting runners.

Propagation

Propagate vegetatively to keep the gold colour true: lift rooted runners or take short stem cuttings and root them in damp soil within a week or two. Division of clumps in spring or autumn also works. Do not raise from seed, which will not come true to the cultivar. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Lysimachia nummularia 'Aurea' is mildly toxic to pets. As a cultivar of Lysimachia nummularia, 'Aurea' shares the species' status: it is not individually listed on the ASPCA Toxic and Non-Toxic Plant lists. Garden sources often call moneywort pet-safe, but this is not ASPCA-confirmed, so treat it as uncertain and verify with a vet if a pet ingests it. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
