The oldest Polypodium cultivar, indeed the oldest clonal herbaceous plant in cultivation. Originating from a 1668 (That's before Carl Linnaeus and binomial nomenclature for reference) collection by Richard Kayse of a uniquely lacerated Polypodium cambricum on a high rocky cliff where it still grows. Beyond the unbelievably cool opportunity to own such a cool part of horticultural history, the fern itself is gorgeous with well cut bipinnatifid fronds, its easy to see why what began as one plant in one spot has now made its presence known across continents and centuries.
