Aponogeton ulvaceus

Aponogeton ulvaceus is one of the most beautiful species in the Aponogeton-family. The leaves are delicate light-green and transparent with fluted margin. A single root can produce more than 40 leaves. This means that the plant is best as a solitary plant in large aquariums. It is relatively tolerant, and thrives in both soft and hard water, particularly if CO₂ is added. There are many varieties of Aponogeton ulvaceus, some of which need a dormant period when the root does not produce leaves.

Aponogeton crispus

Aponogeton crispus looks good in any aquarium with its light-green, transparent leaves. It makes few demands, although growth is always best in soft, slightly acidic water with a nutritious bottom. In such conditions the plant produces a mass of leaves, and it flowers very frequently in optimum conditions. Aponogeton crispus is generally found in ponds that are only filled with water in the rainy season, but it does not need a dormant period in the aquarium.
