When I first moved here I discovered these ferns......I didn't know what they were called and I only saw them after rain and not really very often. They grown on my live oaks and I have numerous live oaks on my property. These ferns are quite amazing - within hours after it rains heavily enough to make the oak branches wet, the ferns grow quickly. They die nearly as soon as the sun hits them or pretty quickly if there is no rain. Their visual impact is quite complicated so there is no real way to spend time drawing them.....you just have to go for the gesture and feel of them. I think this plein air is pretty successful plus I just love the name of them (my neighbor told me).
