Yucca filamentosa ‘Excalibur’ (Adam’s Needle) is a very ornamental, broadleaf evergreen shrub featuring a basal rosette of rigid, sword-shaped, spine-tipped, blue-green to glaucous gray-green leaves. The leaves are edged with an extraordinary number of curly white filaments. They are topped in early to midsummer with a dramatic flowering stalk reaching 5 ft. (150 cm) and bearing panicles of nodding bell-shaped creamy white flowers, about 2.5 in. long (6 cm). Adding architectural height to the garden, this tidy and compact Yucca is great for borders, rock gardens, containers and small gardens.
