General Description:
Utricularia aurea, also known as the large bladderwort, is a rootless aquatic plant that typically thrives submerged below the water surface. This species features finely pinnate leaves, which vary in color from yellowish-green to occasionally dark intensive red in its natural habitat. When cultivated in aquariums, the plant's bladder traps tend to be small or absent. Its flowerstalks, ranging from 15-25 cm in length, produce vibrant yellow flowers and extend above the waterline. Indigenous to the Asian tropics and Australia, U. aurea typically inhabits shallow, still waters and rice paddies.
Aquarium Suitability:
Utricularia aurea is suitable for aquariums, adapting well to both soft and hard water conditions. Its undemanding nature and rapid growth make it a favored choice for aquatic environments. This plant can function as a floating species or be anchored in the substrate like an upright stem plant.
Demands and Hardiness:
U. aurea is categorized as an easy plant to cultivate, thriving in medium to high light conditions with a temperature range of 22-30°C. It tolerates a pH range of 5-8 and requires a supply of carbon dioxide (CO2) in the range of 10-40 mg/l. The plant's nutrient requirements include varying levels of nitrate, phosphate, iron, and potassium.
Aquascaping & Usage:
With its fine-leaved structure, Utricularia aurea adds an aesthetic touch to aquascapes. Often utilized at the water's surface, this plant enhances the visual appeal of the aquarium with its distinctive yellow flowers and lush foliage.
Propagation:
Propagation of U. aurea can be achieved through methods such as fragmentation, cuttings, splitting, or removing daughter plants. These techniques enable aquarists to expand their plant population and maintain a healthy growth cycle.
Habitat and Distribution:
In its natural habitat, Utricularia aurea thrives in shallow stagnant waters and rice paddies across the Asian tropics and Australia. This species' ability to adapt to diverse aquatic environments underscores its widespread distribution and ecological resilience.
