No one can say how many species of plants are used in aquarium hobby, as there are hundreds, if not thousands, of different types of aquatic plants.
Nonetheless, even within this vast array of diversity, there are some plants that immediately catch the eye because they are so unlike any others, almost alien in appearance.
Whether you are new to the hobby or a seasoned aquarist, these weirdly beautiful plants can make a fantastic addition to your tanks, especially if you’re looking for something not ordinary.
In this article, I have compiled a list of the most peculiar, mesmerizing, and strangest plants (spoiler – and more) in terms of their shape and/or coloration.
Here are some of my top picks:
- Subwassertang
- Lucky bamboo (Dracaena sanderiana)
