Polypodium cambricum 'Diadem'



A form that I bought from Julian Reed (National Collection holder) at the Great Dixter Plant Fair.

Mr Tomasz, Polish National Collection Holder of Polystichum says online (Zielono Zakreceni Forum ):

"Variety selected around 1990 by Martin Rickard By his own admission,. As a young plant, it did not stand out in any particular way. After a few years, however, he changed his mind, because it turned out that an adult has a lot of charm. Because it resembled an old, lost variety described by Lowe, 'Diadem', he named it 'Diadem'.
A similar fern was found in Ireland in 1865 by Mr. Morley ( 'Cristatum Morleyi' ) but it is believed that it has also been lost. It grows up to 30.x 8 cm. The top of the leaf and the tips of the leaflets are tipped with small combs."
