Asparagus aethiopicus

Asparagus aethiopicus (Asparagus fern) is a perennial plant that is native to South Africa and has been used extensively in the horticulture industry as a garden ornamental. It is characterized by having a low stature and attractive green branches with small, linear leaves, white flowers, and fruits that are red berries. Asparagus aethiopicus can form dense mats above ground with large tubers and an extensive root system that can suppress other vegetation in shaded settings. This species is listed as invasive in several other parts of the globe where it has escaped from gardens, mostly in wetter areas than California. It has established and is apparently spreading in some natural areas in coastal central and southern California.
