Asparagus scandens is also known as climbing asparagus or asparagus fern. It is a plant native to South Africa in the Asparagus genus, Asparagus fern has been banned in New Zealand after it was listed as invasive species. It is now illegal under the Biosecurity Act to propagate, distribute or sell this plant - either casually or through nurseries - but existing plants are still allowed on private properties.  This plant invades forests and forest edges and smothers understory plants. It will strangle trees and prevents regeneration of canopy species.

Asparagus scandens is a slender scrambling or climbing perennial, with feathery cladodes (green, flattened stems that resemble leaves) usually in threes at each node. Flowers are small solitary and white. These are followed by red berries. The flowers are white, rarely pale pink, 3-4 mm long, solitary in leaf axils. Flowers develop in Sep-Dec and a round red berry about 8 mm in diameter, with a solitary round black seed about 4 mm in diameter. The leaves are narrow lance-shaped, flattened, curved cladodes usually in threes at each node, 5-15 mm long by 0.8-1.5 mm wide, one noticeably longer. Its stems are green and are strongly binding to its support and are much-branched at the top, up to 2 m long. The roots are tuberous.

Found growing in forest remnants, regenerating forest, grassy places, rock walls and hedges. Found on the upper and lower sections of the Te Henui walkway. Spread by birds.
