what is it about ferns?

what is it that attracts so many of us to ferns? is the exquisite detail of the leaflets? or the mesmerizing repetition along the axis? or the feathery delicateness of the elongated fronds? or the abundant lushness? or the pleasing axial symmetry? or do they tickle some lizard-brain memories of the carboniferous swamps?  whatever it is, it all works on me. i can’t get enough of them. ever.
