Blechnum Penna Marina Fern

Blechnum penna-marina, also known as Alpine Water Fern, is a hardy and low-growing evergreen fern that is native to New Zealand. Makes a wonderful rockery fern and is attractive growing near water features. It is also an excellent ground cover and can be used to suppress weeds. A popular ground cover fern.

Low-growing, compact, evergreen fern. Prefers moist, humus-rich soil in a sheltered site. However, it is quite hardy and can be grown in a wide variety of situations.  Surprisingly ferns are not that fussy about soil as long as the small roots (rhizoids) are able to spread through an organic layer with most species preferring good drainage.

Watering is usually necessary during dry summer months and a good mulch will help keep moisture around the roots. Frost Hardy can handle partial sun to shade.

Height up to 25cm in height depending on conditions.
