Ferns are a great choice for low light or high humidity areas like bathrooms. They require more water including regular misting but they are very beautiful delicate houseplants.
Mini Kokedama are about 10cm in diameter.
You can suggest a type of fern you want and I will try my best to supply otherwise it will be what I have in stock.
Generally it will be one of the following...
Blechnum silver lady, Button fern, Davallia Fern, Maidenhair Fern, Pteris Fern
