POLYPODIUM CALIRHIZA 'SARAH LYMAN'
POLYPODIUM CALIRHIZA 'SARAH LYMAN'
Serrated pinnules soften this Californian variant of a Californian native polypody fern, 30cm. Found in 1897 by its namesake in the Napa Valley. 'Calirhiza' is a conflation of P.californicum and P.glycyrrhiza, because it arose as a hybrid between them.
