Dryopteris crassirhizoma is a fern species in the wood fern family Dryopteridaceae.
This semi-evergreen fern grows to 1 m (3.3 ft) tall and broad, with narrowly divided fronds growing in a vase-like shape from a central crown, which is brown in colour. [1]
It has gained the Royal Horticultural Society's Award of Garden Merit. [1]
The acylphloroglucinols (flavaspidic acids [2] ) isolated from D. crassirhizoma show in vitro antibacterial and fatty acid synthase inhibitory activity. [3] Also, the constituents sutchuenoside A and kaempferitrin have in vivo antiparasitic activity. [4]
