Aponogeton ulvaceus
A submerged aquatic plant grown mainly in aquariums, forming a small bulb-like rhizome that produces many wavy, translucent leaves. It thrives in cool to warm, slightly alkaline water with bright light and a sandy or fine-gravel base.
Aponogeton ulvaceus is a submerged aquatic plant in the Aponogetonaceae family. It has a small cone shaped, slightly hairy rhizome about 30 mm (1+1⁄4 in) in diameter. The leaf blades have a base that tapers gradually, pale green in colour (reddish under intense light), over 50 cm (20 in) long and 8 cm (3 in) broad, with a wavy margin on petioles of an equal length, and in appearance slightly translucent. A single bulb may produce up to forty leaves in good conditions. No floating leaves are formed. The yellow flowers are produced on one or two, and sometimes more, erect spikes.
Aponogeton ulvaceus will tolerate most water conditions, but will thrive in slightly alkaline water conditions (pH 6.5-7.5) and a temperature of around 22 to 28 °C (72 to 82 °F), although some are able to survive cooler temperatures. Additional CO2 produces more luxuriant growth. It likes a bright position but will grow in partial shade. In an aquarium it makes a very good specimen plant.
The recommended tank size for this plant is 10 gallons (≈ 38 litres). Its most popular biological filter is the under-gravel filter. An under-gravel filter is simply a plastic plate placed over the bottom of the aquarium.
