| Utricularia graminifolia – the carnivorous foreground plant |
| |
by Ole Pedersen, Troels Andersen and Claus Christensen Utricularia graminifolia (Tropica No 049B) belongs to the most interesting water plants. It is carnivorous and creates an attractive green carpet in the foreground within a couple of months. Utricularia graminifolia may be difficult to start up but once it has gotten a firm grip in the aquarium, it offers a unique experience for the aquarist. The tiny trapping devices may inspire long discussions among family members and friends as carnivorous plants always stimulate people’s curiosity. |

The plant grows partly submerged and partly emerged among the leaf litter. |
Utricularia graminifolia belongs to the bladderwort family (Lentibulariaceae) and originates in SE Asia where it has been found in the southern China, India, Sri Lanka, Burma, Laos and Vietnam. At those sites, it appears as amphibious swamp plant as well as totally submerged in springs and along small streams. Its natural habitat is often shaded and it rarely grows in full sunlight. It always grew in very soft water where we found it and we had severe difficulties keeping it alive during transportation. Fortunately, the plant that is being produced now is much sturdier and thus, more suitable for use in aquaria but it remains a plant for the specialist. Utricularia aurea is another bladderwort which occasionally is found in the shops but it looks completely different with a growth form similar to species of Ceratophyllum and Myriophyllum. |
