Hygrophila corymbosa "Siamensis 53B"

A variety of Hygrophila corymbosa ''Siamensis'', but more bushy with narrower leaves. The difference is less noticeable in older plants. Under water the leaves are light-green and dense. In open aquariums Hygrophila corymbosa ''Siamensis 53B'' grows easily above the water surface, where it forms blue-green leaves and small blue flowers.
Height: 15-30 cm Width: 10-15 cm Light: low-very high Temp.: 20-28'C
Hardness: very soft-hard pH: 5,5-8 Growth: MEDIUM Demands: EASY

Hygrophila polysperma

Hygrophila polysperma is one of the hardiest aquarium plants available. It is particularly good for beginners because it grows in almost all conditions. It normally grows so fast that it is important to prevent it crowding out other plants. The shoots must be pinched out regularly. Leaves lying on the surface form small new plants. H. polysperma varies considerably in leaf shape and colour, depending to some extent on the light supplied.
Height: 25-40cm Width: 10-20cm Light: low-very high Temp.: 18-30'C
Hardness: soft-very hard pH: 5-9 Growth: VERY FAST Demands: VERY EASY

Egeria densa

Egeria densa is a good plant for beginners, and its rapid growth helps create a balance in the aquarium from the start. It can also help prevent algae because it absorbs a great number of nutrients from the water. The plant secretes antibiotic substances which can help prevent blue-green algae (a type of bacteria). The growth rate depends largely on the amount of light and nutrition available. Growth does not stop in unfavourable conditions, but the plant turns light in colour and the tendrils grow thin.
Height : 40-100 cm Width : 3-5 cm Light : medium - very high Temp.: 10-26'C
Hardness : very soft - very hard pH : 5 - 10 Growth ; VERY FAST Demands : EASY

Alternanthera reineckii "roseafolia"

The purple colour underneath Alternanthera reineckii ''roseafolia'' leaves provides an effective contrast to the many green plants in an aquarium - particularly when planted in groups. Good light encourages the leaves to turn red. Most Alternanthera species are difficult to grow, but this one is relatively undemanding. Easy to propagate by nipping off the terminal bud and planting it in the bottom. This also makes the mother plant more bushy, because more side shoots are formed.
Height : 25-50 cm Width : 10-15 cm Light : medium-very high Temp. : 17-28'C
Hardness : soft-hard pH : 5-8 cm Growth : MEDIUM Demands : MEDIUM

Hygrophila corymbosa "angustifolia"

An undemanding plant for large aquariums, which thrives in almost any conditions. If it is not pruned it easily grows above the water surface, where it forms dark-green leaves and beautiful blue flowers. This makes it particularly suitable for open aquariums. It is most beautiful in groups, but the shoots must not be planted too close, because this will prevent light reaching the lower leaves.
Under water Hygrophila corymbosa ''angustifolia'' has relatively narrow leaves which are grouped close together. Plants sold in the shops are normally cultivated above water, and have rounder leaves with larger gaps between them.
Height : 30-60cm Width : 20-35cm Light : medium-very high Temp. : 20-30'C
Hardness : very soft-hard pH : 5,5-8 Growth : FAST Demands : EASY

Hygrophila polysperma ' Rosanervig '

Hygrophila polysperma 'Rosanervig' is normally an undemanding plant. But if you want deep-pink leaves you must provide intensive light. 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.
Height : 20-30+ cm Width : 6-10 cm Light : high-very high Temp. : 18-28'C
Hardness : soft-hard pH : 5-8 Growth : MEDIUM Demands : MEDIUM

Cardamine lyrata

Cardamine lyrata is actually a marsh plant. But it is also a familiar aquarium plant which thrives under water. A characteristic trailing growth form makes it highly decorative, and ''water roots'' often form on the plant itself. Plant in groups, and make sure the water temperature does not exceed 28 degrees for long (this makes the leaves much smaller and the plant more leggy). Also suitable in garden ponds in the summer.
Height : 20-50 cm Width : 15-30 cm Light : medium- very high Temp. : 15-24'C
Hardness : soft-hard pH : 6-8 Growth : FAST Demands : EASY

Bacopa australis

Bacopa australis was discovered in southern Brazil (australis = southern), and it does not come from Australia, as might otherwise be assumed from its name. Like the other Bacopa species, B. australis is also easy to grow in an aquarium. Under certain conditions it creeps across the bottom to form an elegantly decorative light green cushion. When B. australis grows in a good light, the leaves become reddish. It is easily propagated by taking side shoots and planting them in the substrate.
Height : 7-30 cm. Temp. : 15-32'C. pH 6-8. Hardness tolerance : ALL
Growth FAST. Demands VERY EASY.
