Sword-Leaved Holly Fern (Polystichum xiphophyllum)

10.00

This charming garden gem came from a New York Botanical Garden collection made in 1988 at the Green City Mountain Temple near Changdu, China. This species is found no only in western China, but also in northern India, and rarely in Taiwan. The lustrous coriaceous fronds are simply pinnate but with serrated, lobed margins that bear noticeable spiny tips. The tell-tale polystichum "thumb" or acroscopic auricle may be totally separate onthe lowermost pinnae and totally joined onthe uppermost ones. Taxonomic keys give the mature height of this species as 2' but my 25 year old plants have never achieved more than 18".
