What is Creeping Jenny? (And Why Your Aquarium Needs It)
Creeping Jenny, known scientifically as Lysimachia nummularia, is also commonly called Moneywort. You might recognize it from outdoor garden ponds or hanging baskets, where its “creeping” nature allows it to spill beautifully over edges.
What many don’t realize is that this hardy plant adapts wonderfully to being fully submerged in an aquarium. Its defining feature is its pairs of round, coin-shaped leaves that grow along a flexible stem. In good lighting, these leaves take on a brilliant, almost electric, yellow-green color that pops against darker substrates and hardscapes.
But it’s not just a pretty face. The benefits of plant creeping jenny extend far beyond its looks, making it a functional powerhouse for your aquatic ecosystem.
- Natural Filtration: Like all live plants, Creeping Jenny is a nitrate sponge. It actively absorbs waste byproducts from your fish, helping to keep your water cleaner and healthier.
- Oxygenation: Through photosynthesis, it releases vital oxygen into the water column, which is essential for the respiration of your fish and beneficial bacteria.
- Provides Shelter: The dense, curtain-like growth offers a fantastic hiding place for shy fish, fry (baby fish), and invertebrates like shrimp. They love foraging and feeling secure within its leaves.
- Stunning Aesthetics: This is the big one! It can be grown as a background plant to create a wall of green, a midground accent, or allowed to drape over rocks and wood for that signature cascading look.
- Beginner-Friendly: It’s incredibly resilient and adaptable, making it a forgiving choice for those new to planted tanks. You don’t need a high-tech setup to get started with it.
The Complete Plant Creeping Jenny Care Guide
Ready to get started? The best part about Creeping Jenny is its easygoing nature. It doesn’t demand perfection, but giving it the right conditions will reward you with explosive growth and vibrant color. Here’s everything you need to know, broken down in this comprehensive plant creeping jenny care guide.
Lighting Requirements
Light is probably the most important factor for this plant. Creeping Jenny is adaptable, but it truly shines under medium to high lighting. In these conditions, you’ll see dense, compact growth and that iconic bright chartreuse color.
If you have a low-light setup, don’t despair! It will still grow, but it may become “leggy.” This means the space between the leaf sets on the stem will get longer as the plant stretches towards the light source. The color might also be a deeper green rather than a bright yellow-green.
Water Parameters
Here’s where its beginner-friendly reputation really comes from. Creeping Jenny isn’t fussy about water parameters and tolerates a wide range of conditions.
- Temperature: It’s comfortable anywhere between 60-82°F (15-28°C), which covers the entire range of most tropical and unheated community tanks.
- pH: A pH range of 6.0 to 8.0 is perfectly fine.
- Hardness: It can thrive in both soft and hard water.
The key is stability. Like all aquarium inhabitants, it does best when these parameters don’t swing wildly. Regular water changes are your best friend here.
Substrate and Nutrients
While it can pull some nutrients from the water column, Creeping Jenny is a stem plant that develops a robust root system. Planting it in a nutrient-rich substrate will give it a massive head start and fuel lush growth.
If you’re using an inert substrate like sand or gravel, don’t worry! You can easily supplement with root tabs placed near the base of the stems every few months. A good quality, all-in-one liquid fertilizer dosed weekly will also provide essential micronutrients through the leaves.
CO2 Injection: Necessary or Nice-to-Have?
Let’s be clear: CO2 is not required to grow Creeping Jenny. It will grow just fine in a “low-tech” tank without any supplemental carbon dioxide.
However, if you want to see its absolute best, adding CO2 is like hitting the turbo button. With CO2 injection, growth becomes much faster, denser, and the colors will be breathtakingly vibrant. Think of it as an optional upgrade for aquarists who want to push their plant growth to the next level.
How to Plant Creeping Jenny for Maximum Impact
You’ve got your plant, and your tank is ready. Now for the fun part! Following these simple steps on how to plant creeping jenny will ensure it gets established quickly and thrives from day one. These are some of the most important plant creeping jenny best practices.
- Prepare the Plant: Your Creeping Jenny likely came in a pot with rock wool or held together by a lead weight. Gently remove all of this material and rinse the stems and roots under lukewarm tap water.
- Separate the Stems: Don’t plant the whole bunch in one clump! This is a common mistake. Carefully separate the bunch into individual stems or small groups of two to three stems.
- Trim the Ends: Using sharp aquascaping scissors, snip off the bottom inch of each stem. This removes any potentially damaged ends and encourages new root growth from the cut point.
- Plant with Tweezers: Using a pair of aquascaping tweezers, grab a stem and push it firmly into the substrate, at least 1-2 inches deep to anchor it. Plant each stem or small group about an inch apart. This spacing seems wide at first, but it allows light and water to circulate, preventing the lower leaves from rotting and encouraging bushier growth.
- Position for Effect: For a background wall, plant the stems in a dense line across the back of the tank. For the classic draping effect, plant them at the base of a piece of driftwood or a tall rock and let them grow up and over it naturally.
Pro Tip: If you find the stems are buoyant and trying to float up, you can use plant weights (the kind that wrap around the base) or strategically place small stones around the base until the roots take hold.
Propagation and Trimming: Your Source for Infinite Plants
One of the most rewarding parts of growing stem plants is how easy they are to propagate. You essentially get free plants forever! Regular trimming not only keeps your aquascape looking sharp but also provides the cuttings you need to expand your green jungle.
The process is incredibly simple:
- Let a stem grow nice and tall, at least 4-5 inches.
- Using your aquascaping scissors, snip the top 2-3 inches of the plant off.
- Remove the leaves from the bottom half-inch of the new cutting.
- Simply plant this cutting back into the substrate. That’s it! It will quickly develop roots and become a new, independent plant.
Regularly trimming and replanting the tops is the secret to creating a dense, bushy look. The original planted portion will also sprout new side shoots from where you cut it, making the plant even fuller over time. This is one of our favorite plant creeping jenny tips for creating a lush aquascape on a budget.
Solving Common Problems with Plant Creeping Jenny
While Creeping Jenny is tough, no plant is completely invincible. If you run into trouble, don’t panic! Here are the solutions to the most common problems with plant creeping jenny that aquarists face.
Melting After Planting
You just planted your beautiful stems, and a few days later, some leaves are turning transparent and disintegrating. This is called “melting.” It’s perfectly normal! Most Creeping Jenny is grown emersed (out of water) at nurseries. The leaves it grew in the air are not adapted to being underwater. The plant is simply shedding its old leaves to grow new, fully submerged ones. Just be patient and trim away any heavily melted parts.
Yellowing Leaves or Stunted Growth
If new growth is pale, yellow, or seems to have stopped, the culprit is almost always a nutrient deficiency. This is a sign your plant is hungry! Start by adding a comprehensive liquid fertilizer. If the problem persists, place a root tab near the plant’s base to give it a direct source of food.
Leggy, Spindly Growth
As mentioned earlier, leggy growth—long stems with lots of space between the leaves—is a clear sign of insufficient lighting. The plant is desperately stretching to find more light. The solution is to either increase your light intensity or duration, or move the plant to a brighter spot in the aquarium.
Algae on the Leaves
Because it’s a relatively slower-growing stem plant, its leaves can sometimes become a target for algae, especially in new tanks. This isn’t the plant’s fault; it’s a symptom of an imbalance in your tank (usually too much light, inconsistent CO2, or excess nutrients). Address the root cause of the algae, and consider adding some algae-eating crew like Amano shrimp or Otocinclus catfish to help keep the leaves clean.
Sustainable and Eco-Friendly Creeping Jenny Practices
As responsible aquarists, it’s important to think about our impact. Embracing sustainable plant creeping jenny practices is easy and beneficial for both your tank and the environment.
When you first buy your plants, consider sourcing them from sellers who offer tissue-cultured specimens. These are grown in a sterile lab environment, guaranteeing they are free from pests, algae, and pesticides that could harm your sensitive shrimp or fish.
Most importantly, never release aquarium plants or animals into local waterways. Creeping Jenny is considered an invasive species in some parts of North America. It can outcompete native plants and damage local ecosystems. An eco-friendly plant creeping jenny practice is to either dispose of unwanted cuttings in the trash or, even better, share them with fellow hobbyists in your local aquarium club or online community!
Frequently Asked Questions About Plant Creeping Jenny
Is Creeping Jenny a good beginner plant?
Absolutely! It is one of the best. Its hardiness, adaptability to a wide range of water parameters, and lack of a need for CO2 make it a forgiving and highly rewarding plant for anyone just starting their aquascaping journey.
Can Creeping Jenny grow floating?
While it can survive for a while floating on the surface, it will not thrive. It is a rooted stem plant that does best when its base is planted firmly in the substrate where it can draw nutrients and anchor itself properly.
