Description: The desert spoon (Dasylirion wheeleri) is a moderate to slow-growing mounding evergreen shrub. The grass-like succulent leaves radiate from the centre of the plant's apex in all directions.
Stems/Trunks/Caudex: Single, succulents, short-caulescens, unbranched up to 40 cm thick growing to 1,5 m tall (but usually so short it hardly exists ), though often recumbent on the ground. It is usually mounded only; can be pruned to a trunk-like look.
Roots:Thick and fusiform, or spindle shaped (Bogler in press). Young plants usually have two to three large fusiform roots the size and shape of carrots.
Rosette: Large, ball-shaped , with hundreds of long leaves, 120-150 cm in diameter.
Leaves: leaf blade thin, flat, pliable, elongated, 35-100 cm long, 15-20 mm wide, silver-green, bluish green or occasionally green, with a toothed, saw-like margin and split at the tips with frilly fibrelike appendages, teeth yellowish, sharp; petiole base shaped like spoon, hence the common name “Desert Spoon”. Older leaves droop around the base, forming a shaggy mantle that collects water and provides support.
Inflorescence: The flowering stem grows above the foliage, to a height of 5 m tall, and 3-6 cm diameter. The stem is topped by a long plume with thousands of tiny flowers. Female plant inflorescence structure is more rounded, on male plant it is more narrow; the stalk is persistent if not removed.
Flowers: Plants are dioecious, the flowers are insignificant, whitish green to straw-coloured small about 2,5 cm long with six tepals. The colour of the flower determinate the gender of the plant, being more white colored for males and tinged purple-pink for females plants.
Blooming season: may to August.
Fruit: Small brownish, oval, dry-capsule, 5-8 mm long, containing a single seed.
Remark: The similar, but smaller, Dasylirion leiophyllum has teeth that curve toward the leaf base.
