It is a pretty fern with limey green coloured and interesting patterned leaves. It does need some humidity though the ends of the leaves will go crispy without it. I have grouped my humidity loving plants together to form a micro climate which seems better for my crocodile fern.

It’s taken me a while to figure out a good watering schedule for this one. Leaves wilt and dry easily but are super resilient and come back just as easy!
