You’re not alone in this curiosity. The names are confusing, the plants look similar, and the potential for a cheap, beautiful addition to your aquascape is tempting. But you’re right to hesitate and ask the important question: is golden moneywort the same as creeping jenny?
I promise, by the end of this article, you’ll have a crystal-clear answer. We’re going to unravel this botanical mystery together. You’ll not only learn their true identity but also gain the confidence and knowledge to successfully transition this plant from a terrestrial pot to a thriving underwater wonder.

The Big Reveal: So, Are They the Same Plant?
Let’s get straight to the point: Yes, Golden Moneywort and Creeping Jenny are the exact same plant. They are two different common names for the same species, which is scientifically known as Lysimachia nummularia.
Think of it like fish names. One person might call a fish a “Neon,” while another calls it by its full name, “Neon Tetra.” They’re both referring to the same beautiful little fish, Paracheirodon innesi. The plant world is full of these naming overlaps, and it’s a frequent source of confusion for hobbyists.
The key thing to understand isn’t the name, but the form the plant is in when you buy it. Lysimachia nummularia is an amphibious plant, meaning it can grow both out of water (emersed) and fully underwater (submerged). The “Creeping Jenny” you find in a garden center is its emersed form, adapted to growing in moist soil with its leaves in the air.
The “Golden Moneywort” sold in pet stores is often the same plant, but it has either been grown emersed by the nursery or has already started transitioning to its submerged form. Understanding this distinction is the secret to successfully growing it in your tank.
From Garden Path to Aquarium Glass: The Transformation of Creeping Jenny
So, you can use the garden center version, but you need to be prepared for a magical transformation. When you submerge an emersed-grown Creeping Jenny, it has to completely change its biology to survive and thrive underwater. It’s like a superhero changing into their costume!
Here’s what you can expect during this transition period:
- Leaf Shape and Size: The round, coin-like leaves of the emersed form will often give way to slightly smaller, more delicate, and sometimes more elongated leaves on the new submerged growth.
- Growth Direction: On land, the plant “creeps” horizontally. Underwater, while it can still spread, it will often grow more vertically towards the light, creating beautiful, leafy stems.
- The “Melting” Phase: Don’t panic! This is the most crucial part of this is golden moneywort the same as creeping jenny guide. The original, air-breathing leaves are not adapted to underwater life. They will often turn brown, “melt,” and decay. This is completely normal. The plant is shedding its old self and focusing its energy on producing new, fully aquatic leaves.
The trick is patience. As long as the stems remain firm and you see tiny new green leaves sprouting, the plant is successfully making the switch. You can help it along by trimming away any heavily decaying leaves to prevent them from fouling your water.
A Complete Is Golden Moneywort the Same as Creeping Jenny Care Guide
Once your plant has settled in, it’s a wonderfully rewarding and relatively easy plant to care for. It’s a fast grower that can add a vibrant splash of green or gold to any aquascape. Here are the is golden moneywort the same as creeping jenny best practices for lush, healthy growth.
Lighting: The Key to Color and Density
Lysimachia nummularia is not overly demanding, but it truly shines under moderate to high lighting. In a well-lit tank, you’ll be rewarded with dense, compact growth and that signature bright, golden-green color.
If the lighting is too low, the plant will still grow, but it will become “leggy.” This means the space between the leaves on the stem will get longer as the plant stretches desperately towards the light source. It may also lose its lower leaves, resulting in a bare-stemmed look at the bottom.
CO2 and Fertilization: Fueling the Growth
While not strictly necessary, injecting CO2 will supercharge your Golden Moneywort’s growth. It will be more robust, colorful, and dense. If you’re a beginner without a CO2 setup, don’t worry—it can still grow beautifully without it.
What is essential, however, is a good fertilizer regimen. This plant is a “stem feeder,” meaning it primarily absorbs nutrients from the water column through its leaves. A comprehensive liquid fertilizer that contains both macronutrients (Nitrogen, Phosphorus, Potassium) and micronutrients (like iron) is your best friend. Dose regularly according to the manufacturer’s instructions to prevent deficiencies.
Substrate and Planting
Because it’s a water column feeder, the type of substrate isn’t critical. It will grow happily in plain sand or gravel. However, using a nutrient-rich aquarium soil can give it an extra boost, especially as it develops its root system.
When planting, it’s best to separate the bunch into individual stems. Using a pair of aquascaping tweezers, plant each stem into the substrate about an inch apart. This gives each stem access to light and water flow, encouraging bushier growth from the start.
Ideal Water Parameters
This is a tough and adaptable plant, which is great news for all of us! It thrives in a wide range of conditions.
- Temperature: 60-82°F (15-28°C) – It’s comfortable in both cool water and heated tropical tanks.
- pH: 6.0 – 8.0
- Hardness: Soft to hard water is acceptable.
This flexibility makes it a fantastic choice for almost any community tank setup, from a simple guppy tank to a high-tech planted aquarium.
Benefits of Using Creeping Jenny in Your Aquarium
Now that you know how to care for it, let’s talk about the rewards. Exploring the benefits of is golden moneywort the same as creeping jenny shows why it’s such a popular choice for aquascapers of all levels.
- Stunning Color: Its bright, cheerful green provides a fantastic contrast to darker green plants and red plants, making your whole aquascape pop.
- Fast Growth: Looking to fill in a new tank quickly? This plant is a workhorse. Its rapid growth helps create a lush, mature look in a shorter amount of time.
- Nutrient Sponge: That fast growth is fueled by nutrients in your water, including nitrates, which are byproducts of fish waste. It actively helps you maintain better water quality and can even help keep algae at bay by outcompeting it for resources.
- Perfect for Aquascaping: You can use it as a mid-ground “bush” or let it grow tall to create a vibrant background. Regular trimming will encourage it to branch out and become even denser.
- Provides Shelter: The dense foliage offers excellent cover and foraging ground for shy fish, shrimp, and tiny fry, making them feel safer and more secure in their environment.
Common Problems with Golden Moneywort and How to Solve Them
Even the easiest plants can run into trouble. Don’t worry, here are some common problems with is golden moneywort the same as creeping jenny and simple, actionable solutions.
Problem: My new plant is melting and dying!
Solution: This is almost always the normal transition from its emersed to submerged form. As we discussed, the old leaves are dying off. The key is to look for new growth. If you see tiny green buds or leaves forming, your plant is healthy and just needs time. Trim away the decaying parts and be patient.
Problem: The stems are long and sparse, and the bottom is bare.
Solution: This is a classic sign of insufficient light. The plant is stretching to find more. Your options are to increase the intensity of your light, increase the duration it’s on each day (aim for 6-8 hours), or move the plant to a more brightly lit area of the tank. Trimming the tops and replanting them can also help create a fuller look at the base.
Problem: The leaves are covered in algae.
Solution: Algae on leaves is usually caused by an imbalance in the “aquarium triangle”: light, nutrients, and CO2. It could be too much light, inconsistent CO2 levels, or an excess of certain nutrients. Try reducing your lighting period by an hour, ensuring your fertilizer dosing is consistent, and manually removing the algae. Introducing algae-eating shrimp like Amano shrimp can also be a huge help.
Problem: The new leaves are pale or yellow.
Solution: This points to a nutrient deficiency. Yellowing is often a sign of a lack of nitrogen or, more commonly, iron. Ensure you are using a comprehensive liquid fertilizer that contains these essential micronutrients. If you are, consider slightly increasing your dosage.
Sustainable and Eco-Friendly Aquascaping Best Practices
Being a responsible aquarist means thinking about our impact. A key part of a sustainable is golden moneywort the same as creeping jenny approach is propagation. This plant is incredibly easy to propagate. Simply trim the top half of a healthy stem and replant it in the substrate. The trimmed bottom part will sprout new side shoots, and the replanted top will grow into a new stem. You’ll never need to buy it again!
One crucial eco-friendly is golden moneywort the same as creeping jenny tip: NEVER release aquarium plants or animals into local waterways. Lysimachia nummularia can be invasive in some parts of the world, choking out native vegetation. Always dispose of unwanted plant trimmings by letting them dry out completely before putting them in the trash or compost.
Finally, if you buy it from a garden center, be cautious. These plants are sometimes treated with pesticides that are harmless to humans but deadly to invertebrates like shrimp and snails. It’s a good practice to rinse the plant thoroughly and quarantine it in a separate bucket of water for a week or two, changing the water daily, before adding it to your main tank.
Frequently Asked Questions About Golden Moneywort and Creeping Jenny
Can I just take Creeping Jenny from my garden and put it in my fish tank?
Technically yes, but with a big caution. Garden soil contains bacteria and organisms you don’t want in your tank. More importantly, outdoor plants are exposed to pesticides and herbicides. You would need to wash it meticulously and quarantine it for several weeks to ensure it’s safe for your aquatic life. It’s generally safer to source it from a dedicated aquatic nursery or a reputable garden center where you can be sure no harmful chemicals were used.
How fast does Golden Moneywort grow underwater?
Under ideal conditions (good light, nutrients, and CO2), it can grow very quickly, sometimes an inch or more per week. In a lower-tech setup without CO2, growth will be slower but still steady. You’ll likely find yourself trimming and replanting every few weeks to keep it looking its best.
Will my fish eat Creeping Jenny?
Most common community fish like tetras, rasboras, and corydoras will leave it alone. However, notorious plant-eaters like larger Goldfish, Silver Dollars, and some cichlids will likely make a meal of it. Always research your fish’s diet before adding delicate plants.
Is Creeping Jenny a good background or foreground plant?
It’s most commonly used as a mid-ground or background plant. Its vertical growth pattern allows it to create a dense, bright green wall of foliage that looks fantastic behind rocks or driftwood. With very frequent trimming, you could potentially create a low-growing carpet, but this is a high-maintenance approach.
