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 North America, Central America, South America, and the Caribbean. Early reports of the species were confused with the cassava (Manihot esculenta). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, yuca (spelled with a single "c"). It is also colloquially known in the lower Midwest United States as "ghosts in the graveyard", as 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. https://en.wikipedia.org/wiki/Yucca
