Creeping Jenny: Lysimachia nummularia
An adaptable marginal plant with round, bright green leaves that transitions easily from terrestrial to fully submerged growth.
Creeping Jenny
Creeping Jenny, scientifically known as Lysimachia nummularia, is an attractive, aquatic perennial that brings vibrant color and texture to aquascapes. This plant is characterized by its lush, green foliage, which transforms to a striking golden yellow in the autumn months. Its sprawling growth habit makes it ideal for covering the substrate in a naturalistic setting, providing a lush foreground that complements taller plants and driftwood structures.
Care Guide
To maintain optimal growth for Creeping Jenny, it is essential to replicate its natural habitat conditions.
-
Lighting: Provide moderate to bright lighting conditions. Creeping Jenny thrives best in environments where it receives at least 8-10 hours of light daily. Insufficient light can result in leggy growth and diminished coloration.
-
Water Parameters: Ideally, maintain a pH range of 6.0 to 7.5. Water temperature should be kept between 20-25°C (68-77°F), ensuring a comfortable environment for both the plant and any cohabiting fauna.
-
Trimming: Regular trimming is necessary to prevent the plant from becoming overly dominant. Pinch off excess foliage to encourage bushier growth and maintain a balanced aquascape.
Nutrient Requirements
-
CO2: While Creeping Jenny can tolerate low CO2 levels, the addition of CO2 injection systems will significantly enhance growth rates and overall vitality.
-
Fertilization: A balanced aquascaping fertilizer rich in potassium and micronutrients is recommended. Apply liquid fertilizers bi-weekly during the growing season and reduce during the dormant winter months.
Natural Biomes
Creeping Jenny flourishes in various natural environments, contributing to its adaptability in aquascapes. Key biomes to consider are:
These habitats emphasize the plant's versatility and can inspire biotope aquascapes that reflect their natural occurrence.
Livestock Compatibility
Creeping Jenny is an excellent companion for a variety of freshwater livestock. Fish such as Neon Tetras and Guppies thrive in aquascapes featuring this plant, while shrimp species like Cherry Shrimp and Amano Shrimp find shelter and foraging opportunities among its lush growth. This harmony contributes to a biodiverse and dynamic aquatic ecosystem.
