Creeping Jenny (Lysimachia nummularia)
Creeping Jenny is a versatile trailing plant that brings vibrant lime-green to golden-yellow foliage to your aquascape. When grown submerged, it produces long, flexible stems with delicate round to oval leaves, creating a soft, naturalistic texture similar to Hydrocotyle or Bacopa.
Aquatic Growth Characteristics:
- Long, flexible stems that trail horizontally or arch gently upward
- Smaller, thinner leaves than emersed form—round to oval shape
- Lighter green to yellow-green coloration under strong light
- Creeping growth habit, rooting at nodes when in contact with substrate
- Spreads via runners, forming soft mats across the substrate
Care Requirements:
- Lighting: Requires moderate to bright lighting for optimal color and growth
- Substrate: Grows best in fine-grained substrate with good nutrient availability
- Water Conditions: Thrives in soft to moderately hard water with a pH between 6.0 and 7.5
- Water Temperature: Prefers temperatures between 18°C and 26°C

I’ve been growing Creeping Jenny in my 50-liter tank for three months. The plant spreads nicely and adds a soft, natural look. The leaves turn a nice yellow-green under my LED lights. It’s easy to maintain and doesn’t compete with other plants for space.

The plant grows slowly at first, but after a few weeks it starts forming a dense mat. I like the color variation—especially in bright lighting. It works well with my floating plants and doesn’t require much pruning.

Great for beginners. The stems are flexible and don’t break easily. I planted it in a corner of my tank and it spread naturally without needing to trim. The color is vibrant and adds a lot of visual interest.
