Tropica 1-2Grow! Alternanthera reineckii ‘Mini’
This miniture version of the well-known Alternanthera is characterized by compact growth and a slower growth rate. It is particularly suitable for small aquariums or as a foreground plant in larger aquascapes. By careful trimming can you create a dense, red-violet carpet approximately 5 to 10 cm high. High light intensity and addition of CO2 improves the plants growth and overall apperance.
Tropica 1-2Grow! Eleocharis acicularis ‘Mini’
Eleocharis acicularis ‘mini’ has even lower growth than the common Eleocharis parvula and was given to Tropica by Thomas Barr from US. Plant the mini-version in small portions covering a larger area. In short time, a dense carpet will be obtained. Needs light to perform optimal, however, it is one of the most secure species for craeting a carpet – and a minimum of maintenance since leaves stays small (3-5 cm). Suitable for nano-aquariums.
Tropica 1-2Grow! Helanthium ‘Quadricostatus’
Echinodorus ‘Quadricostatus’ from South America has characteristic light-green leaves 10-15 cm long which form a good contrast to the darker aquarium plants. It is most beautiful when planted in groups, each roset becoming 15-20 cm wide. In good conditions it produces runners which spread over the bottom. Very light leaves are a sign of a shortage of micro-nutrients. There is some confusion about the name of this plant, and it has been sold as Echinodorus bolivianus var. magdalenensis.
Tropica 1-2Grow! Littorella uniflora
The appearance of Littorella uniflora makes it an easily recognizable plant in the aquarium. It grows wild on lakeshores of Europe, North America and South America. Tolerates quite low light intensity, but this will add to the length of leaves. Each rosette is planted separately with a distance of a few cm. They will readily send out runners. In time a very characteristic carpet of fat and fleshy leaves – each 2-5 cm long and 0,1-0,3 cm wide – will be created. Littorella uniflora is suitable for terrarium and garden ponds, too.
Tropica 1-2Grow! Staurogyne repens
Staurogyne repens is a fresh green, compact and hardy plant for the foreground of the aquarium and it was found in River Rio Cristalino in the southern Amazonas. Its nearest relative in the aquaristic is Hygrophila but Staurogyne is different with its marked compact, low and bushy stature (5-10 cm) and small green leaves (each stem is 3.4 cm wide). During planting in the aquarium, the longest upright shoots should be cut off and new horizontally creeping shoots will soon form from the plant basis and gradually colonize the gravel.
Tropica 1-2Grow! Cryptocoryne crispatula
Cryptocoryne crispatula var. balansae is from Southern Thailand where there are limestone mountains, and the water can be very hard. Like many other Cryptocorynes it needs to acclimatise before growth starts in earnest. Leaves becomes 20-60 cm long and the single roset plant becomes 15-20 cm wide.
Tropica 1-2Grow! Cryptocoryne undulatus ‘Red’
This red version of Cryptocoryne undulata grows wild in rivers of Sri Lanka.
It is an easy plant, tolerant of very different conditions in an aquarium. Appearance of the plant will partially depend on these conditions.
Low levels of light and nutrients will produce a relatively tall, greenish-brown plant of slow growth. Higher levels of light and nutrition, combined with added CO2, will make the plant grow considerably faster producing shorter leaves of a reddish-brown colour.
Tropica 1-2Grow! Gratiola viscidula
Gratiola viscidula originates from Northern America and is relatively new to the aquatic hobby. The somewhat ‘thorny’ appearance of the submersed form makes it very distinct and easily recognizable. It is quite easy to grow and prefers good light. By regular trimming it can be kept very low, almost carpeting, but will also present itself well as a fore/mid-ground cushion-plant. Each stem is approximately 1-2 cm wide and can become 10+ cm tall. The stem willingly branches and spreads giving a very dense appearance to the plant.
Tropica 1-2Grow! Hemianthus 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. Used to be called Micranthemum micranthemoides.
Tropica 1-2Grow! Heteranthera zosterifolia
Heteranthera zosterifolia from South America is an extremely beautiful plant which forms a lot of side shoots and thus quickly forms a bushy plant group. Stems can become 30-50 cm tall and 6-12 cm wide. In strong light growth is intensive, and the plant must be pruned before it becomes so compact that no light reaches the lower leaves. Water roots often form on the stem. In open aquariums it forms small blue flowers if some shoots are allowed to spread on the surface.
Tropica 1-2Grow! Marsilea hirsuta
Marsilea hirsuta is a carpet-plant from Australia. A fascinating plant, usually delivered with leaves like a four-leaf clover. After a transitional period it develops different types of leaves, possibly a low form with single leaves like a large Glossostigma, or alternatively develop two, three or four-lobed leaves varying in height (from 2-10 cm), depending on the growth conditions. Whichever form the plant adopts, it forms runners and spreads rapidly round the aquarium.
Tropica 1-2Grow! Riccia fluitans
Japanese Takashi Amano has inspired many aquarium owners to keep the 1-5 cm tall cosmopolitic moss, Riccia fluitans, submerged. It can be kept down by tying it to a stone with a piece of fishing line, but new shoots always grow towards the surface, so it may be necessary to prune it with scissors. Riccia fluitans thrives best with added CO2 and in good growing conditions small oxygen bubbles form on the leaf tips. As a traditional floating plant offers good protection for young fish.
Tropica 1-2Grow! Rotala ‘Bonsai’
Rotala ‘Bonsai’ is best described as a compact, moderate growing version of Bacopa caroliniana. Plant in small groups and trim often. Cuttings may be re-planted in the group to achieve a more dense group or carpet. At high light may the tip of the stems become reddish, at lower light will the leaves become larger and the plant less compact. Rotala ‘Bonsai’ are particularly suitable for nano-aquariums.
Tropica 1-2Grow! Salvinia auriculata
Salvinia auriculata is a cosmopolitic floating fern, 1-3 cm, that grows quickly if there is sufficient nutrition and light. Light leaves are a sign of a shortage of micronutrients. It tends to shade light from the plants at the bottom. Salvinia varieties have small hairs on their leaves, making them water resistant.
Helps prevent algae by shading parts of the aquarium and using nutrients in the water. Grows very big in the wild and in optimum conditions. A decorative plant for open aquariums.
Previously named Salvinia natans.
Tropica 1-2Grow! Vesicularia dubyana ‘Christmas’
A moss speciality from Brasil, 1-3 cm tall, called “Christmas tree moss”, because of its side branch structure which distinguishes it from ordinary Vesicularia dubyana and looks like fir tree branches. It is more demanding than ordinary Java moss and grows more slowly. It attaches readily to roots and stones, and as it spreads in the water it needs pruning to keep its shape attractive. See also Taxiphyllum barbieri.
Tropica 1-2Grow! Bacopa Caroliniana
Bacopa caroliniana originates from US and has been used as an aquarium plant for many years. Stems become 10-30 cm long and 3-4 cm wide. Apart from relatively good light it makes few demands. Its slow growth rate makes it one of the few stem plants that do not need much attention. Like most stem plants, it is most decorative when planted in small groups. Easy to propagate by cuttings; take a side shoot and plant it in the bottom.
Tropica 1-2Grow! Cryptocoryne wendtii ‘Green’
Cryptocoryne wendtii ‘Green’ is suitable for small aquariums with heights from 5-15 cm and a roset from 8-15 cm wide. When grown in an open space the leaves will virtually lie on the bottom. Like most other Sri Lanka Cryptocorynes, it also grows well in hard water.
