The Toothless Sotol (Dasylirion longissimum syn: Dasylirion quadrangularis) is a slow growing durable evergreen shrub that looks like a miniature palm with a large fountain-like clump of very stiff grassy leaves, eventually forming (after many many years) a solitary trunk , most resembling the genus Xanthorea, the grass trees of Australia. (completely unrelated, though) Even the flower spikes look similar. This appearance makes it very easy to identify. Withstanding intense drought, they can live more than 150 years. It is possibly the most beautiful “sotol”.
