About This Plant
Mentha aquatica Large Leaf Aquatic Mint is a favorite with water gardeners because it is delightfully fragrant, and produces miniature lavender-pink blooms that attract many butterflies. The leaves are ovate to ovate-lanceolate and measure 1-3 inches. The plant grows in sun to part shade in moist soil or water to 2" deep. The foliage can be used in teas and jellies.

Forgiving enough for hobbyists with one tank of experience. Watch lighting and nutrient levels for best growth.
CO2 & Fertilization
CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.
Tank Size & Setup
Works in tanks 10 gallons and up. Match the plant size to your tank depth for the cleanest aquascape.
Aquascaping & Placement
Position to suit your aquascape — most placements work as long as light reaches the leaves.
Tank-Mate Compatibility
Compatible with the full range of community-tank species — tetras, rasboras, livebearers, corydoras, and most other peaceful freshwater fish do not damage the foliage.
Common Care Issues
Slow initial growth
Most aquarium plants pause for 2-4 weeks after planting while they convert from their nursery-grown emersed form to fully submerged growth. New leaves that emerge underwater will look thinner and slightly different — this is the plant adapting, not a problem.
