Summary
Spineless Yucca, also called Giant Yucca, is a Central American native evergreen with a thick woody trunk; leaves are spineless, blue-green, sword-shaped and arranged in spiral rosettes, forming a tree-like plant with a dramatic vertical presence and, on mature plants, white flowers on tall stalks in early summer; indoors it often appears as tall canes in multi-stem arrangements and is known for rugged, low-maintenance growth and few pest problems. Culture and practical aspects include bright sun to partial shade with well-drained soil; drought-tolerant and overwatering avoided; suitable for outdoor use in warm climates or indoors as an architectural specimen; propagate via stem cuttings or offsets; pests are rare though scale can occur; hardy in USDA zones 9b–11b; leaves contain saponins and ingestion can be harmful to humans and pets.
