Spanish dagger, palm lily, mound-lily yucca
Vascular – Exotic
Herbs - Monocots
Occur naturally on coastal dunes and shell mounds near the Atlantic, from North Carolina to north-east Florida.
An erect evergreen shrub with swordlike leaves about 5 cm wide and 0.6-0.9 m long originating from a basal rosette. The leaves are bluish or grayish green with smooth margins and pointed tips. They tend to bend near the middle and arch downward. In summer mound-lily yucca puts up a showy 6-8 ft (1.8-2.4 m) spike of fragrant flowers that are white with purplish tinges, pendant and about 7.6 cm across. Mound-lily yucca stays in a stemless rounded clump 2-5 ft (0.6-1.5 m) across and about the same height for several years, but eventually develops a trunk or stem which elevates that clump of leaves above the ground as much as 1.8-2.4 m. In older plants the stem develops branches and each terminus has its own rosette of leaves.
The cultivar, Nobilis has dark green leaves and Variegata has leaves with yellow margins.
