Cardamine lyrata, known as Japanese Cress or Chinese Ivy, is a popular, easy-to-grow aquatic plant from East Asia, prized in aquariums for its clover-like, bright green leaves and creeping growth, forming dense bushes or climbing décor like driftwood; it thrives in cooler water, moderate to high light, and is easily propagated by cutting stems, making it great for beginners and creating contrast in aquascapes, especially for covering fry or shrimp.
