Asparagus setaceus, commonly known as common asparagus fern, asparagus grass, lace fern, climbing asparagus, or ferny asparagus, is a climbing plant in the genus Asparagus.[2] Despite its common name, the plant is not a true fern, but has leaves that resemble one.[3]
Naming
Originally described by the German botanist Carl Sigismund Kunth, its Latin specific epithet setaceus means "hairy".[4]
Description
Asparagus setaceus is a scrambling evergreen perennial with tough green stems and leaves, which may reach several metres in length. The leaves are actually leaf-like cladodes up to 7 mm long by 0.1 mm in diameter, which arise in clumps of up to 15 from the stem, making a fine, soft green fern-like foliage. Sharp barbed thorns occur on the stem. Occurring from spring to autumn, the small greenish-white bell-shaped flowers are 0.4 cm long, and are followed by small green berries, which blacken with maturity.[5] They are reportedly toxic upon consumption. If eaten, they can lead to diarrhea and abdominal pain.[6]
Distribution
It is native to Southern Africa, extending south west as far as Calitzdorp in the Karoo.
It is grown elsewhere as an ornamental plant. It has become an invasive species in several locations where it has been introduced.[7]
Cultivation
Asparagus setaceus is cultivated as an ornamental plant, for planting in garden and containers, and as a house plant. The attractive foliage is also used in floral arrangements. It is hardy to 1 °C (34 °F), but does not tolerate being frozen. Therefore in temperate zones it is normally cultivated indoors in bright, indirect light.[8]
This plant has gained the Royal Horticultural Society’s Award of Garden Merit.[8]
Invasive species
This hardiness has helped it become a weed in Lord Howe and Norfolk Islands.[9] Other areas that regard it as an invasive species and noxious weed include the North Coast of New South Wales,[10] and Queensland, Australia.[11]
