About This Plant
Hydrocleys nymphoides The Water Poppy may be one of nature's most graceful floating plants. This impressive plant adds an unbelievable carpet of foliage and visual intensity to any pond's edge. Its 2-4 inch dark green, heart shaped leaves grow along, long trailing stems. It has an often-abundant scattering of quaint yellow flowers. The blooms are cup-shaped with a contrasting red and brown center that stretch 2 to 2-1/2" above the water's surface. The flowers bloom between June and August, though the plant thrives year-round in warmer climates.

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

Aquascaping & Placement
Position to suit your aquascape — most placements work as long as light reaches the leaves.

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.
