Invasive Species

Agave americana is a large, rhizomatous succulent that grows in a wide range of conditions including cliffs, urban areas, woodlands, grasslands, riparian zones, beaches and sandy areas, and rocky slopes. A. americana is tolerant of wind, salt, high temperatures, and extreme drought. It can grow in shallow, very dry, low fertility soil and can colonise bare sand. It is grown for many reasons- ornamental, medicinal and agricultural. In South Australia Agave americana mainly invades disturbed sites, road sides and coastal vegetation. It may also harbour introduced animal species, such as rabbits, making feral animal control more difficult.

Usage [3]  The plant contains saponins. An extract of the leaves is used as a soap; The roots are used according to another report; It is likely that the root is the best source of the saponins that are used to make a soap; Chop up the leaves or the roots into small pieces and then simmer them in water to extract the saponins. Do not over boil or you will start to break down the saponins; There is a report that the plant has insecticidal properties, but further details are not given; A very strong fibre obtained from the leaves is used for making rope, coarse fabrics etc; A paper can also be made from the leaves; The thorns on the leaves are used as pins and needles; The dried flowering stems are used as a waterproof thatch; The plants are used in land-reclamation schemes in arid areas of the world;
Vegetative Spread Rate [2]  None
