We’ll cover what this plant is, its amazing benefits for Florida tanks, a step-by-step setup process, a detailed care guide, and how to solve common problems. Let’s dive in and turn your aquarium into the vibrant underwater paradise you’ve always imagined.
What Exactly is Creeping Jenny (Lysimachia nummularia)?
Before we get into the nitty-gritty, let’s get properly introduced. Creeping Jenny, known scientifically as Lysimachia nummularia, is that plant with the charming, coin-shaped leaves you’ve likely seen spilling over hanging baskets at your local home and garden store.
Here’s the most important thing to understand: Creeping Jenny is technically a marginal or bog plant. This means in nature, it loves to grow along the edges of ponds and streams with its roots in the water and its leaves in the air. This is different from a true aquatic plant that spends its entire life cycle underwater.
“So, can it even grow in an aquarium?” Absolutely! But knowing its nature is the key to success. Because it’s not a true aquatic, it requires some specific conditions to make the switch to fully submersed life. When you give it what it needs, it rewards you with brilliant green or golden stems that create a stunning curtain of color in your tank.
The Unique Benefits of Creeping Jenny in Florida Aquariums
So, why go to the trouble with this particular plant, especially here in the Sunshine State? The answer lies in its unique advantages that make it surprisingly well-suited for our local conditions. Here are some of the top benefits of creeping jenny in florida aquariums.
- Hard Water Tolerant: Much of Florida has liquid rock coming out of the tap—water that is high in minerals, or “hard.” Many sensitive aquarium plants struggle with this, but Creeping Jenny is incredibly adaptable and often thrives in the exact conditions that cause others to fail.
- Fast-Growing Algae Fighter: When happy, this plant grows quickly. This is fantastic news for your tank’s ecosystem! Fast-growing plants are masters at soaking up excess nutrients (like nitrates) from the water column, essentially starving out pesky algae before it can take over.
- Stunning Visual Appeal: The way Creeping Jenny grows creates a beautiful vertical accent. Its long, trailing stems and bright, round leaves can form a dense green backdrop or a flowing curtain of color, adding depth and a sense of lushness to your aquascape.
- Perfect for Beginners: Don’t worry—this plant is very forgiving! Its resilience makes it a great choice for those just starting their aquascaping journey. It gives you clear signs when it’s unhappy, making it easy to learn and adjust your care routine.
- Versatile Growth Options: You can grow it fully submerged, or you can let it grow emersed—meaning it’s planted in the tank but allowed to grow out of the top. It looks incredible trailing down the side of a rimless tank or out of the back of a hang-on-back filter.
Your Step-by-Step Creeping Jenny in Florida Guide: From Store to Substrate
Ready to get started? Bringing this plant home and getting it settled is easy if you follow a few simple steps. This is exactly how to creeping jenny in florida for long-term success.
Step 1: Selecting Your Plant
You’ll likely find Creeping Jenny sold in plastic pots or as bunches at your local fish store or even a garden center. Look for plants with vibrant, green or golden leaves and no signs of browning or decay. If possible, try to find plants that have already been grown submersed, as this will make their transition to your tank much easier.
Step 2: Preparation is Key
Once you get your plant home, don’t just toss it in the tank! Take a moment to prepare it. Gently remove it from the pot or bunch and rinse it thoroughly under lukewarm tap water. This removes any pesticides or unwanted hitchhikers. Carefully trim away any dead or yellowing leaves and trim the roots back slightly to encourage new growth.
Step 3: Planting for Success
Planting Creeping Jenny correctly is crucial. Because it’s a stem plant, you should plant each stem individually into your substrate. Space them about an inch apart. This might seem tedious, but it ensures that light and water can reach the lower portions of every stem, preventing the dreaded “bottom melt.”
A good, nutrient-rich substrate is beneficial, but not strictly necessary if you plan to fertilize the water column. Use planting tweezers to push each stem about 1-2 inches deep into the gravel or sand. This anchors it securely while it establishes its new root system.
The Ultimate Creeping Jenny in Florida Care Guide
Once your Creeping Jenny is planted, keeping it happy is all about maintaining the right environment. Following these creeping jenny in florida best practices will ensure it doesn’t just survive, but truly thrives.
Lighting: The Most Important Factor
If there’s one non-negotiable for Creeping Jenny, it’s strong lighting. This is the single most critical element for success. Under high light, the plant will grow densely with short spaces between its leaves, creating that lush, bushy look we all want. In low light, it will become “leggy,” with long, bare stems reaching for the light, and will eventually shed its lower leaves.
CO2 and Fertilization
Does it need CO2 injection? No, it’s not strictly required. However, adding CO2 will result in explosive, vibrant growth. If you’re running a low-tech setup, you can still succeed, but growth will be much slower.
Fertilization is a must. Creeping Jenny is a hungry plant. It will benefit greatly from a comprehensive liquid fertilizer dosed regularly. Look for one that contains both macronutrients (Nitrogen, Phosphorus, Potassium) and micronutrients (especially iron, which prevents yellowing). Adding root tabs near its base will also give it a fantastic boost.
Water Parameters
This is where Creeping Jenny shines for us Floridians. It’s not fussy!
- Temperature: It prefers cooler water, ideally between 60-78°F (15-25°C).
- pH: A range of 6.0 to 8.0 is perfectly fine.
- Hardness: It does well in both soft and hard water, making it a champion for our mineral-rich tap water.
Trimming and Propagation
One of the best parts of this plant is how easy it is to propagate. As the stems grow tall, simply snip the top 3-4 inches off with a pair of aquascaping scissors. You can then take that cutting and plant it directly back into the substrate. It will quickly grow roots and become a new plant! Regular trimming encourages the original plant to send out side shoots, making the whole stand much bushier.
Solving Common Problems with Creeping Jenny in Florida Tanks
Even with the best care, you might run into a few hiccups. Don’t panic! Here’s a look at the most common problems with creeping jenny in florida tanks and how to fix them.
Problem: “Melting” Shortly After Planting
The Cause: This is the most common issue. The plant is transitioning from its emersed form (grown in air) to its submersed form (grown underwater). The old leaves, which were adapted to air, are dying off as new, water-adapted leaves grow in.
The Solution: Be patient! This is a normal process. Do not uproot the plant. Trim away the decaying leaves and ensure your lighting and nutrient levels are good. Within a week or two, you should see new, healthy growth emerging.
Problem: Leggy Growth with Bare Bottom Stems
The Cause: This is almost always a sign of insufficient lighting. The plant is stretching to reach the light source, and the lower leaves aren’t getting enough light to survive, so the plant sheds them.
The Solution: Increase your lighting intensity or duration. If you can’t upgrade your light, trim the healthy tops and replant them, discarding the bare lower stems. This keeps the look fresh and full.
Problem: Yellowing Leaves
The Cause: Yellowing leaves, especially new growth, typically point to a nutrient deficiency. The most common culprit is a lack of iron, but it could also be a shortage of nitrogen.
The Solution: Start dosing a comprehensive liquid fertilizer that contains iron and other micronutrients. If the problem persists, check your nitrate levels. If they are at zero, you may need to dose nitrogen as well.
Sustainable and Eco-Friendly Creeping Jenny in Florida Practices
As responsible aquarists, our duty extends beyond our glass boxes. This is especially true in a state with such a delicate ecosystem as Florida. Embracing sustainable creeping jenny in florida practices is non-negotiable.
IMPORTANT: While not currently on Florida’s official prohibited aquatic plant list, Lysimachia nummularia is considered invasive in other parts of the United States. It can easily take over local wetlands if it escapes.
Here’s how to be an eco-friendly creeping jenny in florida hobbyist:
- NEVER Release Plants into the Wild. This is the golden rule. Never, ever dump aquarium plants or water into local ponds, lakes, canals, or storm drains. This can introduce invasive species and devastate local habitats.
- Dispose of Trimmings Properly. Do not just flush them down the toilet. The best method is to let the plant trimmings dry out completely until they are brown and crispy. Once fully dead and dry, they can be thrown in the trash or composted.
- Source Responsibly. Whenever possible, buy your plants from reputable local fish stores or other hobbyists. This minimizes the risk of introducing pests and supports our local aquarium community.
Frequently Asked Questions About Creeping Jenny in Florida
Can Creeping Jenny live fully submerged forever?
Yes, but with a condition. It can live its entire life submerged as long as it has high light and a steady supply of nutrients. It is less of a long-term marathon runner and more of a sprinter. In optimal conditions, it will thrive, but if conditions decline, it will fade faster than a true aquatic plant.
Does Creeping Jenny need CO2 to grow in an aquarium?
It is not an absolute requirement, but it is highly recommended for the best results. Without CO2, growth will be much slower and the plant will be less dense. With CO2, you’ll see the fast, lush growth that makes this plant so desirable.
Why are the bottom leaves of my Creeping Jenny falling off?
This is a classic sign that the lower parts of the plant are not receiving enough light. The dense top growth is shading out the bottom. The solution is to either increase your light intensity or to regularly trim and replant the tops to keep the stand from getting too tall and dense.
Is Creeping Jenny safe for shrimp and snails?
Yes, absolutely! It is completely safe for all aquarium invertebrates and fish. In fact, shrimp love to graze on the biofilm that grows on its leaves, and it provides great cover for shrimplets and small fry.
