Overview
Cardamine lyrata is an aquatic plant of the mustard family from the cool waters of East Asia. Its small, round, light green leaves are arranged alternately on thin stems and give the aquarium a light, airy look. It likes cool water: it grows best between 15 and 22 °C, and when kept constantly above 24 °C its leaves become smaller and the plant weakens. For this reason it is better suited to unheated aquariums and shrimp tanks kept cool than to tropical aquariums.
Planting and Placement
- Stems are planted in groups of 3–5, 3 cm apart and 3 cm deep.
- It is placed in the midground or background, in an area that gets good light.
Care and Fertilization
- Light: Medium.
- CO₂: Not required.
- Temperature: Should be kept below 24 °C.
- Fertilizer: Occasional liquid fertilizer is enough.
- Trimming: Cut from the top; the cut tops root easily and can be replanted.
