Korean rock fern
© Richie Steffen / Great Plant Picks
Often sold as an indoor houseplant this beautiful and useful fern is quite hardy in our climate (to USDA zone 6). Korean rock fern is a charming, small, evergreen fern with a neat appearance. Each frond is delicately laced with black veins that accentuate its rich, dark green leaves. It is a slow grower, only reaching about 12 inches tall and gradually forming a small clump. The fronds are held very upright and are finely divided, creating an eye-catching yet refined look. This is a must for any shady rockery and can be useful and long-lived as a container plant. Combine Korean rock fern with pale greens or variegated plants to make the dark foliage stand out in the shade. It's a great choice for small spaces.

- Culture Notes
- This fern grows best in rich moist to well-drained soil, but will tolerate sand or clay. Provide regular watering during dry weather to keep the fronds from drying out. This fern grows well in light to deep shade. Though it is evergreen the fronds should be cut down in late February or March, before the new fronds emerge.
