My grandmother's favorite plant was the fern and I often find myself referencing the hardy perennial she planted many years ago still waving its huge fan-like fronds in my garden. With similar reliability, the typo Refernc* comes up 17 times in OhioLINK. Ferns are weird and prehistoric, sort of like flying dinosaurs, and the collection and cultivation of them was a preoccupation of the Victorians. Ferns get by with neither seeds nor flowers, reproducing by means of spores. Plus, if it weren't for Fern, Wilbur would never have become Some Pig.
