One common misunderstanding about potted plants is that people think these plants need to stay in their pots.... Really, the potted plants are grown this way for two main reasons: They are ideally used in the pet industry to simplify inventory and to protect the plant from cichlids or other fish who like to dig up plants.
When your potted plant arrives, we recommend taking the plant out of the pot and removing as much of the wool substrate from the roots before placing in your aquarium. So you now ask: "Why even bother buying potted as opposed to loose forms of the same plant for a cheaper price?" Well...these plants here not only ship better, but they also have an established root system and therefore your chances of growing this plant successfully will be greater.
