Asparagus Ferns
Asparagus scandens, Asparagus densiflorus Asparagus plumosus

Multi-branched prostrate and/or climbing herbs 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.

Asparagus species are highly invasive environmental weeds however some species are still in nursery production.

These 'ferns' overtake natural species by developing dense thickets that deprive other plants of light and nutrients as well as destroying habitat. The most effective means of removal is to dig out the growth crown which lies just below the soil surface.

Among the highly recommended varieties are 'Royal Mantle', 'Bronze Rambler', 'Bedspread' and 'Gin Gin Gem'.

Plants ideal for mass planting and covering of large areas. The red toothbrush flowers occur in spring and autumn. These species grow to about 0.3 m high by 2 m across and are frost tolerant. Grown as 'living mulch', they will trail over banks or walls and attract nectar-feeding birds. Mass planting is highly recommended.
