Western Sword Fern
(Polystichum munitum) - The dark green fronds
of this fern grow to 1 to 5.9ft tall, in a tight clump spreading out radially
from a round base.
It grows best in a well-drained
acidic soil of rich humus and small stones. Sword ferns are very tough and can survive
occasional dry periods, but do well only with consistent moisture, light
sunlight, and prefer cool weather to overly warm. In cultivation, they also
respond well to regular, light applications of fertilizer.
