What Plants Flower in the Aquarium?
Flowering plants are suitable for aquariums. Several plants produce flowers in the aquarium. Some of these plants are overwater, while others are underwater.
These plants include Rotala, Amazon swords, Orchid Lily, Hornwort, and Anubias.
Do Aquatic Plants Have Flowers?
