Description: Yucca gigantea (syn: Yucca elephantipes), popularly called "spineless yucca" as well as "elephant yucca", is an evergreen species that may grow into a rather large palm like shrub or small tree with a very noticeable swollen base that tapers up to a slender branched trunk similar to Nolina recurvata. Both trunk and branches produce large, compact clusters of dark green leaves. The leaves are pliable and lack the sharp spines on the tips that are so characteristic of most yuccas, and this is one big yucca, getting up to 9 or more m tall, but usually less than m. This plant has become very popular as a houseplant since the end of the 1970s and its variants are currently being used in most modern interior landscapes. Its worldwide popularity as a houseplant has created a minor industry in Central America. Y. giganteais a member of the agave family and is also closely related to the lilies. Like other yuccas, this one has white bell shaped flowers borne on tall stalks above the foliage in summer.
Stem: With age the trunk becomes rough and thick, and when mature it develops a swollen base and often branches just a few decimetres off the ground.
Leaves: In a spiral columnar rosette, linear-lanceolate, strap-like, soft, glossy green, succulent, 60-120 cm long and about 5-7.5 cm wide plane or a little plicate. Margins smooth or rough with obscure teeth and with soft green tip, 5-10 mm long. Sometime a little roughened on the dorsal ridges. The selection, 'Variegata' has leaves with creamy yellow margins.
Inflorescence: Paniculate, glabrous, up to 1 metre tall with many creamy white flowers produced within the rosette of leaves. Style short, oblong. Unlike some species, this yucca does not die after flowering.
Blooming season: Yucca gigantea dependent on rain in the wild; in cultivation, late spring is the usual flowering season. Flowers perfect (male and female parts in each flower)
Fruit: Indeihscent, brown, fleshy oval and up to 2.5 cm long. Yuccas require a specific moth for pollination, and if the right moth isn't around, you won't see fruit develop even though the plant

produces flowers.
Seeds: Nearly circular, 8-10 mm in diameter, not winged.
Note: The official name is now Yucca gigantea but the species is most widely known today as Yucca elephantipes. The first mention of that name was by Eduard von Regel in February 1859. He claimed that a different species, Yucca aloifolia, was sometimes known as "Yucca elephantipes" when grown in European gardens because of its thickened stem base. However, since he did not intend to offer Y. elephantipes as the actual correct name, this was not a valid publication. In a major article on yuccas and allies in 1902, William Trelease also used the name Y. elephantipes, referring to Regel's 1859 publication. This came too late though, as Yucca gigantea had by then already been previously established. Charles Lemaire published the name Yucca gigantea in November 1859. This is the name used by the World Checklist of Selected Plant Families as of January 2014, although other sources use Yucca guatemalensis, published by Baker in 1872.
