In its shape this agave resembles A. americana though the leaf edges do not show sharp spines and the narrower foliage is not bent downwards. However, the tip is just as dangerous to anyone nearby. It does grow faster and develops a short, thick trunk. Flowers are creamy white. The genus' name derives from the Greek agavos which means 'admirable'. Easily grown in all arid regions, and as with many other desert plants, agaves do not like fertilisers and prefer soils with low organic content. Water logging in pots or rock may kill agaves. Healthy specimens are usually pest free, but mealy bugs or scales can easily be washed off the huge leaves. The flowering stem is stunning, but results in a dead foliage clump that needs to be disposed of carefully. However, offsets make new plants easily. Plants do not flower before the age of 10, but may take up to 30 years before doing so and dying. This species produces tough fibres that are used for matting, twine, sandals or brushes. Sisal for rope is probably the best known product. Native Americans made also medical use of agaves. Other species of agave suitable for planting in Riyadh, or occasionally seen there, are: Agave colorata; Agave palmeri; Agave parryi spp; Agave weberii.
