Hey there, plant lovers! Discover the versatile Moneywort, a plant that thrives in gardens and aquariums alike. This comprehensive guide covers everything from identifying its two main types and providing essential care tips to distinguishing it from its look-alike, Creeping Charlie. Whether you’re a seasoned gardener or an aquarium enthusiast, dive into the fascinating world of Moneywort!
Discovering the Two Types of Moneywort
Moneywort, often called Creeping Jenny, enlivens spaces with its vibrant green foliage and cheerful yellow flowers. Understanding the two distinct types is key to successful cultivation.
Terrestrial Moneywort: Lysimachia nummularia
This garden variety of Moneywort spreads across the ground or cascades from hanging baskets. Its round, coin-like leaves give rise to the nickname “Moneywort.” Bright yellow, cup-shaped flowers add a burst of sunshine.
Garden Care Tips:
- Light & Location: Adaptable to full sun or partial shade, offering flexibility in placement.
- Watering: Prefers consistently moist, well-drained soil. Regular watering is especially important during hot weather.
- Hardiness: Thrives in USDA Zones 2-10, tolerating a wide range of climates.
- Maintenance: Regular trimming and occasional division prevent overcrowding and maintain a neat appearance.
Aquatic Moneywort: Bacopa monnieri
This Moneywort variety flourishes underwater, making it a popular aquarium plant. Its smaller, oval leaves and delicate white or lavender flowers create a tranquil underwater landscape.
Aquarium Care Tips:
- Lighting: Requires bright light, and some hobbyists suggest CO2 injection to enhance growth.
- Trimming: Regular trims maintain its shape and prevent overgrowth within the tank.
- Water Quality: Clean, well-circulated water is essential for healthy growth. Regular water changes are crucial.
Moneywort vs. Creeping Charlie: Key Differences
While often confused, Moneywort and Creeping Charlie have distinct characteristics:
| Feature | Moneywort | Creeping Charlie |
|---|---|---|
| Stems | Round | Square |
| Flowers | Bright yellow, cup-shaped | Lavender, funnel-shaped |
| Leaves | Round, oppositely arranged | Kidney-shaped, alternately arranged |
Essential Moneywort Care Guide
Successfully growing Moneywort, whether in your garden or aquarium, relies on understanding its basic needs.
1. Light & Location
Moneywort thrives in bright, indirect light. In aquariums, 10-12 hours of light per day is ideal. Brighter light promotes bushy growth, while dimmer conditions may result in leggy stems. CO2 and nutrient supplementation can enhance growth in aquariums. [live-native.com, everythingfishkeeping.com]
2. Water & Humidity
Consistent moisture is crucial. Terrestrial Moneywort prefers moist soil and benefits from high humidity (65-80%). Aquatic Moneywort needs submerged conditions or consistently wet roots. It can also grow hydroponically. [everythingfishkeeping.com]
3. Soil & Substrate
Terrestrial Moneywort thrives in standard garden soil. For aquatic environments, aquarium soil is ideal, though gravel or sand can be used with careful planting using tweezers. [everythingfishkeeping.com]
4. Fertilization
Moneywort has low nutritional needs. Initial fertilization during planting is often sufficient. Over-fertilizing can be detrimental. [live-native.com]
5. Pruning
Regular pruning maintains shape, prevents overcrowding, and encourages bushier growth. [pondinformer.com]
6. Propagation
Moneywort is easily propagated through stem cuttings. Simply take a cutting and plant it in soil or substrate. [nextaquarium.com (implied based on the title)]
7. Troubleshooting
- Algae (Aquariums): Maintain optimal water parameters and perform regular water changes to prevent algae growth. [pondinformer.com]
- Leggy Growth: Insufficient light often causes leggy growth. Move the plant to a brighter location.
- Yellowing Leaves: May suggest poor water quality or nutrient deficiency. Check water parameters and consider adding fertilizer if needed.
Creeping Jenny vs. Moneywort: Clarifying the Confusion
The terms “Creeping Jenny” and “Moneywort” often create confusion. While Lysimachia nummularia is widely known as Creeping Jenny, it’s sometimes referred to as Moneywort due to its coin-like leaves. Bacopa monnieri, a distinct aquatic plant, is also called Moneywort. This shared common name leads to misunderstandings. [onlineflowergarden.com]
| Feature | Creeping Jenny (Lysimachia nummularia) | Moneywort/Water Hyssop (Bacopa monnieri) |
|---|---|---|
| Environment | Terrestrial (groundcover) | Aquatic |
| Leaf Shape | Round, coin-like | Oval, succulent-like |
| Leaf Color | Bright green | Light green |
| Flower Color | Yellow | White or purple |
| Growth Habit | Spreading, potentially invasive | Submerged or floating |
Research into Bacopa monnieri‘s medicinal uses, particularly in traditional medicine, is ongoing. Some studies suggest potential cognitive benefits, but further research is needed to fully understand its effects and potential drug interactions. Consult a healthcare professional before using it for medicinal purposes.
Is Moneywort Invasive?
Moneywort (Lysimachia nummularia), or Creeping Jenny, is considered invasive in many regions due to its rapid growth and ability to smother native vegetation. Its dense mats can disrupt water flow and negatively impact ecosystems, particularly near water bodies. [Invasive Plant Advisory Committee (IPAC)]
Effective control may involve manual removal, ensuring complete root removal, and the judicious use of herbicides, especially wetland-approved versions like Rodeo, for larger infestations. Prevention through responsible planting and early detection are crucial.

Additional Considerations:
- Medicinal Uses: Moneywort has historical medicinal uses, but scientific evidence is limited. Always consult a doctor before using any plant for medicinal purposes.
- Invasive Potential: Terrestrial Moneywort can be invasive. Plant responsibly and monitor its growth to prevent it from outcompeting other plants.
- Cultivar Variations: Different Moneywort cultivars offer unique leaf and flower variations.
