Yucca elata is the hardiest south west trunking Yucca in our Massachusetts climate. Very easy to grow and requires no winter protection.

The yucca is the state flower for the state of New Mexico. I love finding them in all stages of development in the desert.

Native tree Yucca to the US southwest and Mexico... has whitish edges along the thin, relatively soft leaf blades, that are a dull green. Looks a bit like Yucca rostrata, only has greener leaves. Flowers form WAY above the plant, too, which sets it apart. Roots have saponin used to make soap. Great landscaping plant- good specimen for a cactus garden.
