Cardamine lyrata is actually a marsh plant from Japan. But it is also a familiar aquarium plant which thrives under water with 20-50 cm long stems. A characteristic trailing growth form makes it highly decorative, and ‘aerial’ roots often form on the plant itself. Plant in groups, and make sure the water temperature does not exceed 28 degrees C (this makes the leaves much smaller and the plant more leggy). Also suitable in garden ponds in the summer. ..
This beautiful variety with the dark, hammered leaves is named after 'Tropica'. When grown in an open space the leaves will virtually lie on the bottom. It is suitable for small aquariums with leaves from 10-15 cm, and a rosette from 10-20 cm wide. Like most other Sri Lanka Cryptocorynes, it also grows well in hard water...
Used to be called Micranthemum micranthemoides. Hemianthus micranthemoides from North America is a graceful plant whose small, arched leaves make it look like a miniature version of Egeria. It has a characteristic trailing growth in intensive light, so it can be used as a foreground plant (stems from 10-20 cm tall, 2-3 cm wide). A compact group of Hemianthus micranthemoides is very beautiful with its small, light-green leaves. In terrariums the plant forms a compact cushion.
Hygrophila corymbosa 'Siamensis 53B' is a variety of Hygrophila corymbosa 'Siamensis'. This Hygrophila 'Siamensis 53B' forms an incredible amount of side shoots and becomes bushy relatively rapidly. Stems becomes 15-40 cm tall and 7-12 cm wide. Its beautiful bright green leaves are narrower than the regular 'Siamensis' and it can achieve red-brown leaves in good light conditions. An undemanding, fast growing plant that must be pruned frequently to maintain a bushy growth.
Hygrophila polysperma 'Rosanervig' is normally an undemanding plant. But if you want deep-pink leaves you must provide intensive light. Stems becomes 20-40 cm tall and 5-8 cm wide. The distinctive colouring of the light leaf ribs is probably caused by a virus which prevents chlorophyll from being produced in the cells around the leaf ribs, making them white. However, this virus does not affect other plants in the aquarium. ..
This bamboo-looking stem plant is not a grass. It comes from Asia, where it often grows in rice fields.The growth is upright, but the plant branches out willingly when it is cut back. The leaf is light green, approx. 1cm wide and 3-5cm long. The stem apex becomes reddish when exposed to CO2 and strong light. Due to quick growth, the longest shoots require ongoing cut back and some of the tops can be replanted, in order to maintain a beautiful and varied group of plants. ..
