Sorrowful Holly Fern (Polystichum luctuosum)

8.00

The species name of this handsome evergreen fern refers to the profusion of black papery scales that adorn the supporting framework.  The sudued dark green foliage gives this fern a somber elegance which is enhanced by the precise acute tips and twice-divided pinnae.  This species has often been confused with and is sometimes sold as Polystichum tsus-simense and P. maybarae (syn. P. tsus-simense maybarae), both of which are 3 times divided, not 2 times divided, in their pinnae.  Since these ferns naturally occur in South Africa, Japan, Korea, Taiwan and China, cold tolerance may vary somewhat depending on where the original stock is from.  Asian stock is considered more reliably cold hardly and thus far our trials with this fern have showed it to be reasonably cold tolerant.  In mild climates it favors fairly moist, (but not soggy) humus-rich soil in light shade, while in harsher more extreme climates it prefers a somewhat protected shaded site.
