Polystichum tsus-simense 'K Rex'

K Rex Rock Fern

K Rex Rock fern (Polystichum tsus-simense ‘K Rex’), is almost twice as large as Korean Rock Fern¬†having ¬†18″ to 24″ fronds.

It has a dark and dusky cast balanced by a subtle luminescence which gives it an attractive elegance in the garden or a flower arrangement. Like all but one of the Polystichums, it is an evergreen. This fern is best used in good shade and rich soil, but highlighted with lighter green to yellow complementary plants. Hostas are a good option.

Just introduced into the trade it can be enjoyed in Zones 6 to 9.
