Description

This uncommon stem plant was introduced under erroneous names such as "Arthraxon sp." and "Murdannia keisak", probably from tropical Asia. However, it is probably a not yet identified Cyanotis species, possibly also Belosynapsis ciliata. It belongs to the Commelinaceae family as well as Murdannia keisak but differs from the latter by smaller size and more compact growth. When it grows as a terrestrial plant, it develops long, creeping or hanging, branching shoots. Roots appear on the nodes. In its submerged form, it grows upright, with smaller, lighter green leaves than in the terrestrial form. Its rigid stems resemble bamboo shoots, therefore it was already called "Aquarium bamboo".

Cyanotis sp. is primarily a terrestrial plant, even though it can grow under water. As submerged plant, it grows relatively slowly and needs good nutrient and CO2 supply as well as medium to strong lighting. On the contrary, it is easy, fast growing and does not need much light when it is grown as land plant, similar to the related Tradescantia species. It thrives best in a nutrient-rich, moderately moist bottom such as customary potting soil, even as houseplant. Also wet substrate and shallow water are tolerated. The plant is easily propagated by cuttings. In its terrestrial form, it can be cut into short cuttings with few nodes and put into the soil. At least one node should be buried.

As aquarium plant, Cyanotis sp. provides an interesting accent, especially as a group in the aquarium midground. It is a smaller, slower growing alternative to Murdannia keisak. The terrestrial form is very suitable for terrariums and paludariums, e.g. as groundcover, hanging down on terrarium walls or as shore plant, creeping from the land part into the water.

Please be aware that the submerse form of this plant could contain snails and other invertebrates.

In Europe, this plant was introduced into trade under the erroneous name "Arthraxon spec.". Arthraxon is a genus in the true grass family (Poaceae). The plant sold under the name "Arthraxon" in Asia and the USA was identified as Sphaerocaryum malaccense (a true grass), however, the plant presented here might look similar but is not a true grass. Instead, it belongs to the Commelinaceae family.
Thomas Rudolph (the Netherlands) has found some blue flowers on plants that were cultivated emersed, which fit the characteristics of the genus Cyanotis. The other characteristics of the plant also point in that direction, however, its exact species has not been determined yet. It was probably imported from South-East Asia.
The genus Cyanotis contains over 50 species that are found in the Asian and African tropics and subtropics down to northern Australia. They grow in moist to dry habitats. (read more)
