Water Lettuce
Water lettuce can be used in water gardens, ponds, or containers both indoors and outdoors. This plant’s foliage only grows about 6 inches tall, but its dense root system under the water can grow up to 20 inches deep. It is a very fast grower once mature and is considered an invasive plant in certain areas.
Water lettuce is great for cleaning the water of decomposition byproducts and is often used to keep the water healthy for fish and aquatic life. This plant also reduces algae blooms by blocking sunlight in the water and by using up the nutrients needed for the algae to bloom. It can be grown in water gardens with fish, but larger fish, such as koi, cichlids, and goldfish, may nibble on and damage the plants.
