38. Succulent
Succulents are the type of houseplants that often aren’t on the list of oxygen plants, but large succulents like Jade Trees can be great oxygen generators and air purifiers. Look for succulent species with larger, more porous woody stems and leaves like Jade or large Echeveria varieties. Succulents are easy to grow if you resist the urge to overwhelm them. Succulent species can be ignored for long periods until they even begin to wrinkle before watering. They can survive dry deserts, like desert plants, much better than sitting in the water where they will quickly mold and rot.
