Gahnia setifolia is a tall grass species found in lowland forest and scrub throughout the North Island and upper South Island. The leaves of this species are sharp, so careful placement is needed. It is a large plant that is not suitable for smaller gardens. Overall height is 1-2.5m. The flowering stems are at least as long as the leaves and carry dark drooping panicles that are followed by shiny reddish brown fruit. This is an imposing and graceful plant which prefers a moist soil and will grow in either full sun or shade.
