How to identify Aloe yucca (Yucca aloifolia)

Aloe yucca, also known as Spanish bayonet

Aloe yucca displays sharp-tipped, sword-shaped leaves that lack filaments along their margins, characteristic for identification. Predominantly, in spring to late summer, it showcases a striking, central display of bell-shaped flowers gathered in large, hanging clusters. These blossoms signify the plant's flowering maturity, as aloe yucca ceases vertical growth post-flowering, instead developing lateral buds that become new shoots. It often produces multiple offshoots near its base, contributing to its dense, thicket-like growth habit.
