Wardian case

A Wardian case is a special kind of terrarium, like an aquarium but for plants instead of fish! It was invented by a doctor named Dr. Ward so it's named after him. Inside the Wardian case, there is special air and soil that helps plants grow better, since it keeps them away from the dust, wind and rain that can hurt them. The case also has special glass walls that let the sunlight in, which plants need. So with all these special features, the Wardian case helps plants stay safe, healthy, and happy!
