Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40-50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (Manihot esculenta). Consequently, Linnaeus mistakenly derived the generic name from the Ta-no word for the latter, yuca (spelled with a single "c").It is commonly found growing in rural graveyards and when in bloom the cluster of (usually pale) flowers on a thin stalk appear as floating apparitions.
