7-10, 12-24

Form & Character: Basally-spreading, pale, spherical, reserved, peaceful, less obtrusive than other yuccas, Spanish architecture.

Growth Habit: Evergreen, mostly herbaceous, monocot perennial subshrub, slow, acaulescent (stemless), and basal to 2-feet tall with equal spread (6 feet in height with flower stalks), some basal offsetting with age.

Foliage/Texture: Strap-like leaves are 2- to 3-feet long, finely serrated, strongly glaucous (gray blue), taper to a sharp but flexible tip; coarse texture.

Flowers & Fruits: Pale whitish-green flowers with 6 petals are born singly along a 6- to 8-feet flower stalk; fruit a capsule, rarely grow bulbils.
