Fishbone water fern is a terrestrial, tufted fern of wet habitats. Blechnum species are commonly referred to as water ferns, as they are usually found in wet areas, growing in a variety of habitats from slopes to low-lying, poorly drained areas. It has a creeping horizontal underground stem (rhizome) which may form an erect sturdy trunk. It has bright-green fronds that are clustered near the tip of the rhizome. Each frond is supported by a stem (stipe). This kind of plant is mostly used in different gardening related works like sheltered gullies, beside water areas and ferneries.
