Yucca Rigida - Mexican Blue Yucca
Native to northeastern Mexico, this upright Yucca slowly forms a trunk-like stem, reaching up to around 2m tall. The trunk sometimes branches to have multiple heads.
The trunk, covered by older leaves bent downard, is topped with rosettes of spear-shaped, blue-green leaves, very stiff and sharply pointed, with fine teeth along the margin. Leaves typically reach around 70cm long, pointed upwards.
Flowers are creamy white, blossoming in spring, bell shaped, growing in panicles on flower stalks.
Semi hardy, can tolerate temperatures down to -5°C.
