Utricularia graminifolia is an attractive perennial native to the marshes and flood grounds of Asia. It is a grass-like member of the carnivorous bladderwort family and, like all bladderwort family plants, U. graminifolia has a unique ‘bladder trap’ feature designed to capture small nitrogen- and phosphorous-rich crustaceans. Hobbyists should also avoid pairing this plant with burrowing fish as it is sensitive to disruption.
Dry-starting U. graminifolia is recommended; otherwise, it may be necessary to artificially attach plants to substrate until they are rooted. Lighting may be kept low for the first 6 to 8 weeks following planting but should be increased thereafter; chronic low light will result in longer, darker foliage while intense lighting will promote robust, rapid growth. U. graminifolia requires water column fertilization, and although not strictly necessary, CO2 supplementation will boost its growth significantly. Soft water and an acidic substrate also encourage healthy growth. Hobbyists should trim this plant regularly to cultivate a neat, lawn-like appearance. Runners may be clipped and re-planted to propagate.
