Cardamine lyrata – Fast-Growing, Flowing, and Ideal for Cool Planted Tanks
Cardamine lyrata, also known as Japanese Cress, is a unique and fast-growing aquatic plant with delicate, clover-like leaves and a trailing or creeping growth habit. Native to East Asia, this versatile plant thrives in cooler water conditions and adds a lush, natural appearance to aquascaped tanks. Its light green color and fine texture make it a standout in foreground to midground placements, where it can be left to trail along the substrate or trained to grow upward.

Cardamine lyrata is best suited for peaceful, planted tanks and does especially well in cooler water aquariums. It pairs beautifully with nano fish, shrimp, and other low-demand aquatic plants. Its creeping habit can form a dense, carpet-like layer with frequent trimming, or be allowed to grow vertically for a more dramatic look.
