Water Plants
Common Water Hyacinth - Eichhornia crassipes 

As beautiful as its lilac and periwinkle-tinged blossoms may be, the common water hyacinth is known as being a problematic and invasive species which can easily cover lakes and ponds, thus affecting water flow and preventing sunlight from reaching other aquatic plants. If tended carefully in man-made ponds however, it can provide a good source of food and shelter for goldfish and assist in keeping water clean and oxygenated. As such, it is not at all uncommon to see these plants in places such as botanical gardens where their violet blooms and waxy, spade-shaped leaves spread across the water with majesty. They grow in clusters, with their bulbous, spongy stalks typically climbing no more than 6 inches above the water's surface. Water hyacinths prefer a tropical desert to subtropical or rainforest zones. They are native to these parts, but if tended properly, can make beautiful and thriving additions to any home garden or pond. Water hyacinths grow and spread quickly with low maintenance as they are able to reproduce both sexually and clonally. They do not grow well in water with a salinity above 15%, but have a resilient response to high levels of pH in soil. Kept in a controlled environment, these flowers are an easy addition to beautify any pond. 

Fairy Moss - Azolla filiculoides 

While it may be debatable as to whether you'll have any elfin creatures visiting to feast upon your fairy moss, this fuzzy foliage is certainly a favorite to nibble among koi fish. Fairy moss, which is distinguishable by its tiny clusters of reddish-purple tinged leaves, is a water-dwelling plant that grows best in hardy zones 5-10. This plant is short in height, typically resting mostly atop the water. They are low maintenance plants, but it is recommended to bring several clumps indoors during the winter to replenish the pond's supply come warmer temperatures, as frost may damage the moss. In addition to providing a delicious treat for pond fish, fairy moss can also aid in keeping algae levels managed.
