Cardamine lyrata sp (Vietnam)
Cardamine lyrata sp. Vietnam is a Vietnamese form of Cardamine lyrata, a fast-growing cool-water plant. It produces bright green, rounded leaves on soft trailing stems and can be grown rooted in the substrate or left floating at the surface.
Care tip: Keep it cool. Cardamine lyrata grows best below about 78°F — in warm tropical tanks the leaves shrink and the stems stretch and get leggy. It is a good fit for unheated and room-temperature aquariums.
Cardamine lyrata grows as a fast, soft-stemmed stem plant that reaches 8 to 20 inches when left untrimmed. Trim the tops regularly and replant the cuttings to keep it bushy and at the height you want. In nano tanks, treat it as a midground plant that needs frequent trimming, or let the stems float at the surface instead.
Care is easy: moderate lighting, CO₂ optional, temperatures of 60–78°F and a pH of 6.0–7.5. Regular liquid fertilization keeps the leaves green and full-sized. It propagates readily from cuttings and often forms aerial roots along the stems.
In the aquascape, the rounded leaves add soft texture in the midground to background, and floating stems make excellent cover for fry and shrimp in breeding tanks.
