Japanese tassel fern belongs to the evergreen group. Its leaves are hardy to about -20°C if sheltered from sun and wind. In any case the plant is fully hardy to about -30°C. Upright growing leaves are long fronds made of dark green, glossy, leathery leaflets, often with hairy indumentum on the reverse. It does not require that much moist soil, it will even do well in a partially shaded rockery. Dislikes being overwet in winter. Cut off all last-year’s leaves in the spring to encourage new growths.
