In Singapore: Palm Lily, Moundlily Yucca, Soft-tipped Yucca, 丝兰属 (Grown in Singapore)
Yucca gloriosa is an evergreen shrub from the southeastern US, grown for its stiff, sword-like leaves and tall white flower spikes. It is very tough and needs sun, good drainage and little care.
Yucca gloriosa, also known as Spanish dagger, mound lily yucca and other common names, is a species of flowering plant in the asparagus family, native to the southeastern United States. Growing to 2.5 m (8 ft), it is an evergreen shrub. It is widely cultivated as an ornamental for its architectural qualities, and has reportedly become established in warmer climates in the wild in various parts of the world.
The plant is widely cultivated in warm temperate and subtropical climates, and valued as an architectural focal point. It has reportedly escaped from cultivation and naturalised in Italy, Turkey, Mauritius, Réunion, Guam, the Northern Mariana Islands, Puerto Rico, Argentina, Chile and Uruguay. In landscape use, little maintenance is needed other than the removal of dead leaves when the shrub nears its ultimate height. The plant is very hardy, without leaf damage at −20 °C (−4 °F), and can handle brief snow and freezing temperatures, as well as long periods of drought. Yucca gloriosa, and the cultivars 'Variegata' and Bright Star = 'Walbristar' have gained the Royal Horticultural Society's Award of Garden Merit.
Yucca gloriosa grows on exposed sand dunes along the coast and barrier islands of the lower East Coast of the United States, often together with Yucca aloifolia and a variety formerly called Yucca recurvifolia or Y. gloriosa var. recurvifolia, now Y. gloriosa var. tristis. Large, endemic populations can be found in the beach and dune environments of coastal North Carolina. In contrast to Y. gloriosa var. tristis, the leaves of Y. gloriosa var. gloriosa are hard stiff, erect and narrower. On the other hand, Y. aloifolia has leaves with denticulate margins and a sharp-pointed, terminal spine.
