Asparagus Ferns
Asparagus aethiopicus 'Sprengeri' Asparagus plumosus and plumosus 'Nana'

Multi-branched prostrate and/or climbing herb from the lily family that form a dense underground mat of rhizomatous roots. The fern-like branches grow to 0.6 m high and up to 2 m wide with a covering of small sharp spines. These natives from South Africa have small white-pink clusters of flowers in late summer which ripen to bright red, orange or black fruits.



  • By dumping of garden waste. The seeds are readily dispersed by birds and small mammals.

Although Asparagus Ferns are highly invasive environmental weeds, some species are still in production. These 'ferns' will overtake natural species by developing dense thickets that deprive other plants of light and nutrients as well as destroying habitat.

Please note: All other Asparagus species except the cultivated Asparagus officinalis have the potential to become invasive weeds.
