Yuccas are belong to Asparagaceae family (formerly Agavaceae). They can be evergreen perennials, shrubs or trees, with dense or loose rosettes of stiff, sword-shaped leaves and tall panicles of bell-shaped flowers. There are about 40 species and 30 subspecies of yucca, all of them are belong to New World. Although they live in tropics and subtropics, many of them are very hardy and some withstand -30°C.
Yucca gloriosa is a species of yuccas in the family Asparagaceae. It is native to subtropical southeastern USA from the Outer Banks of Virginia and North Carolina to Florida and Alabama. Yucca gloriosa grows on sand dunes along the often together with Yucca aloifolia and a variety called Y. gloriosa var. tristis. In contrast to Y. gloriosa, Tristis varieties leaves are softer, recurvated and wider than usual gloriosa.
Soft Tipped Yucca is an evergreen shrub. The plant is known to grow to height 4 meters. It is caulescent, usually with several stems arising from the base, the base thickening in adult specimens. The long narrow leaves are straight and very stiff, growing to 30–50 cm long and 3-4 cm wide. They are dark green with entire margins, smooth, rarely finely denticulate, acuminate, with a sharp brown terminal spine. Inflorescence is a panicle up to 250 cm long, of bell-shaped white flowers, sometimes tinged purple or red. Fruit is a leathery, elongate berry up to 8 cm long.
Yucca gloriosa is widely cultivated in warm temperate and subtropical climates, and valued as an architectural focal point. In a domestic environment, the plant has average water requirements, and 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. but is subject to injury and decay by winter damp and snow. Leaf ends are less sharp than those of the similar Yucca aloifolia.
Soft Tipped Yucca thrives in sandy, well-drained soil, in heat, full sun, also withstand in shade. Propagation is done by seeds, clump divisions or stem cuttings. Established plants are very drought resistant. The plant tolerates maritime exposure as well. Plants do not flower every year, requiring hot summers to initiate flowering. The flowers are produced in the autumn contrast to most of the yuccas which they flower in spring. The scent of the flowers is most pronounced at night. In the plants native environment, its flowers can only be pollinated by a certain species of moth. This moth cannot live in Turkiye and, if fruit and seed is required, hand pollination is necessary. A range of selected cultivars are available in the horticultural trade, including forms with variegated leaves, Yucca gloriosa variegata is one of the well known.
Yucca gloriosa has been known to cause skin irritation and even allergic reactions upon contact. The leaf points are also sharp enough to break the skin.
