Polystichum Tsus-simense 14cm Pot
Common Name: Korean Rock Fern

Polystichum tsus-simense, commonly known as Korean Rock Fern or Korean Tassel Fern, is a species of evergreen fern native to Korea, China, and Japan. It belongs to the Polystichum genus, which comprises many fern species known for their attractive foliage and adaptability to different growing conditions.

Appearance: Korean Rock Fern has glossy, dark green fronds that grow in a rosette-like arrangement. The fronds are leathery and can reach a length of about 30 to 60 cm. Each frond is composed of multiple pairs of leaflets, which are deeply lobed and have serrated edges. The leaflets give the fern a fine, delicate appearance.

Growth habit: This fern grows in a clumping habit, with new fronds emerging from the center of the plant. Over time, it can form a dense mound of foliage, making it a visually appealing addition to gardens or container plantings.

Light and temperature: Polystichum tsus-simense thrives in partial shade to full shade. It prefers cool to moderate temperatures and is known for its ability to tolerate colder conditions compared to many other fern species.

Watering and humidity: Korean Rock Fern prefers consistently moist soil. It is important to keep the soil evenly moist but not waterlogged, as overly wet conditions can lead to root rot. It benefits from regular watering, especially during dry periods. While it appreciates humidity, it can tolerate average indoor humidity levels.

Soil and fertilisation: Plant Korean Rock Fern in well-draining soil rich in organic matter. It can adapt to a range of soil types but prefers slightly acidic to neutral soil. A slow-release balanced fertiliser applied in spring can help provide nutrients for healthy growth.

Care tips: Remove any dead or damaged fronds regularly to maintain the plant’s appearance. Korean Rock Fern is generally low-maintenance once established. Mulching around the base of the plant can help retain moisture and regulate soil temperature.

Korean Rock Fern, with its attractive fronds and ability to tolerate colder conditions, can be a great choice for shady areas in gardens or as an indoor plant. It adds texture and visual interest to various settings and can thrive with proper care.
