Asparagus Setaceus “Asparagus Fern”

The Asparagus Fern, or Asparagus setaceous, is one of 215 species of asparagus that range from small ground cover plants to sizeable shrubs.

Latin name
Asparagus setaceous

Pronunciation
(“asp-ah-ra-GUS set-AY-she-ous”)

Common name
Asparagus Fern

Origin
Southern and Eastern Africa

A distinguishing feature of all Asparagus is the complete lack of leaves – these are reduced to tiny scales. The feathery foliage, that gives the plant is fern-like appearance (and common name), are called phylloclades and they are actually flattened branches that carry out the same function.

Asparagus setaceous is a fine example of an ornamental asparagus and has delicate foliage held almost horizontally from stiff, dark green stems. Under the right conditions, small white flowers are produced which may develop into deep purple berries (which are toxic).

The specific name, setaceous, means hairy or bristly and is a good example of the scientific name being very descriptive.

Asparagus species are not ferns at all, and are actually most closely related to plants such as Dracaena and Agave.

Did you know?

Asparagus setaceus is actually a member of the same plant family as edible asparagus (Asparagaceae).

Asparagus setaceus contains irritating compounds that can cause mild stomach upset, vomiting or skin irritation if eaten or touched by pets or small children.

caring for your plant

Light

Medium-high light.

Watering

Keep soil moist, but not wet and allow to dry out a little between watering.

Pruning

Dead foliage can be removed by cutting back to the stem.

Feeding

A weak solution of fertilizer can be added to the water at every watering.

pest & diseases

In dry atmospheres, two-spotted spider mites can be troublesome and difficult to control. They can be deterred by regular misting of the foliage with tepid water.

Where the Asparagus Fern originates from

Asparagus setaceus is a Southern African plant, reaching as far south-west as Calitzdorp.

Our plants are grown in Ecoponic, an alternative to soil. Officially known as a vulkaponic substrate, it replaces traditional compost with a clean, mineral-based medium that helps protect peatlands.

According to the IUCN UK Peatland Programme, “A loss of only 5% of UK peatland carbon would be equal to the UK’s annual greenhouse gas emissions.” As well as storing carbon, the natural wetlands where peat is found are critical to the survival of plants and wildlife. Ecoponic also improves plant health and uses water more efficiently.
