Blechnum fluviatile

The kiwikiwi or star fern, Blechnum fluviatile, is an evergreen fern native to New Zealand and Tasmania, where it can be found growing the the damp, moist areas near water.

This species has narrow, deep green fronds and is the perfect partner for plants that enjoy similar growing conditions, like candelabra primulas. It's not fully hardy, so will require winter protection in colder areas.

For best results, grow Blechnum fluviatile in moist, well-drained, humus-rich soil in partial to full shade. Provide with shelter from cold, drying winds. Mulch around clumps each year with a generous amount of home-made compost or leaf mould.
