Aponogetons grow from a bulb and, can usually be purchased either as just a bulb or grown out as a plant. There are many forms the plants can take. The lovely Madagascar lace plant is one of the most attractive of the Aponogetons
. There's a small one pictured to the left.
Most Aponogetons will grow in almost any reasonable conditions, including under lower light levels. Many of them will bloom readily in the aquarium. The blossom stem is rather delicate and easily damaged. If left undamaged the small blossoms can produce seeds that will grow into new small plants.
