Epiphytes/Rheophytes
Rheophytes , more commonly known as Epiphytes in the hobby, are aquarium plants such as Anubias, Bucephalandra and more that propagate differently when compared to stem plants. The plants in this section do not need to be planted in aquarium soil and can be attached to hardscape or aquarium decor. This section will also contain moss, which is not an epiphyte but can be attached to aquarium decor and hardscape!
They are typically low tech and rather hardy, but care should be taken to do additional research to ensure it thrives in your setup!
