Japanese Tassel Fern
Polystichum polyblepharum, the Japanese tassel fern, is one of the most rewarding evergreen ferns you can grow in a UK garden. Its common name comes from the way each new frond unfurls in spring: the croziers arch over and bow their tips, scattering golden-brown scales that catch the light like tassels. The mature fronds settle into a glossy, deep green rosette with a wonderful sheen rarely seen in other hardy ferns, holding their colour right through the coldest months.
This is a plant prized for poise and structure. It forms a tidy, shuttlecock-shaped clump of finely divided, leathery fronds, building slowly into a specimen around 60cm tall and 90cm wide over two to five years. It earns its place at the front of our Hardy Exotics range and holds the RHS Award of Garden Merit, a reliable sign of good garden performance.
How and where to grow it
Like most tassel ferns, it is a shade-dweller. Give it a cool, sheltered position in partial or full shade, ideally on a north or east-facing aspect where the midday sun cannot scorch the fronds. It is not fussy about soil type and will grow happily on chalk, clay, loam or sand, provided the ground stays moist but well-drained and reasonably rich in leaf mould. A spring mulch keeps the roots cool and the moisture in.
- Position: partial to full shade, sheltered from cold drying winds
- Soil: moist but well-drained, any pH
- Hardiness: fully hardy across the UK, evergreen down to about -15C
- Eventual size: roughly 60cm x 90cm
Care could hardly be simpler. There is no pruning to speak of; simply trim away any tired or weather-damaged fronds in late winter, just before the fresh growth emerges. It is equally at home in a shady border, a woodland planting or a large container of loam-based compost, and pairs beautifully with hellebores, hostas and spring bulbs. Among genuinely hardy ferns, few combine evergreen reliability with this much shine.
Every Japanese tassel fern we send out is nursery-grown, well-rooted and carefully selected, ready to establish quickly and reward you for many years.
-
Yes. The Japanese tassel fern is fully hardy across the UK, tolerating temperatures down to around -15C. It holds its fronds through winter, giving you evergreen structure when most of the border has died back.
-
This is a shade-lover. It thrives in partial to full shade and dislikes hot, dry, full-sun positions, which can scorch the fronds. A cool, sheltered spot under trees or on a north or east-facing border is ideal.
-
It forms a neat, shuttlecock-shaped clump roughly 60cm tall and 90cm across, reaching its full size in about two to five years. The arching fronds spread outward rather than running, so it stays well behaved.
-
Yes. It does very well in a container of loam-based, free-draining compost kept in shade. Water regularly so the compost never dries out, and it makes a handsome year-round specimen for a shady patio or doorway.
-
There is no reported toxicity to people or pets for this fern, so it is considered a safe choice for family gardens. As with any plant, discourage pets and small children from chewing the foliage.
