Nolina Explained

Nolina is a genus of tropical xerophytic flowering plants, with the principal distribution being in Mexico and extending into the southern United States.^{[1] [2] [3] [4]} They are large, dioecious plants.^[5]

Some botanists have included the genus Beaucarnea in Nolina. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Former alternative placements include Nolinaceae and Agavaceae. The genus is named for 18th century French arboriculturist Abbé C. P. Nolin.^[6] Members of the genus are known as beargrasses, some of which are cultivated as ornamental plants.
