'Yucca recurvifolia' from the website Trees and Shrubs Online (treesandshrubsonline.
An evergreen shrub up to 6 or 8 ft high, more or less branched. Leaves at first glaucous, 2 to 3 ft or even more long, 11⁄2 to 21⁄4 in. wide, tapering to a fine stiff point, all but the upper leaves much recurved. Flowers creamy-white, 2 to 3 in. across, in an erect panicle 2 to 3 ft high, not so tall nor standing so clear of the leaves as in Y. gloriosa, and with the flowers more loosely arranged; the parts of the flower as in Y. gloriosa. Fruit 2 to 21⁄2 in. long; seeds not glossy, about 1⁄3 in. long.
Native of the coast region of the south-eastern United States, especially of Georgia; introduced in 1794. This is the commonest and most easily cultivated of yuccas, and although not so striking as Y. gloriosa in flower, is a more graceful plant and hardier – or, at any rate, resists snow and damp better. It flowers in late summer, and withstands the smoke of London admirably. It associates well with a formal arrangement of paths and lawns, and gives a very pleasing exotic effect.
