Chloride, Arizona. We always called this ground-hugging variety, with the slightly bluish cast, "Spanish dagger" when I was a kid, but evidently that's so broadly applied as to be useless. (Wikipedia claims that "Spanish dagger" is applied only to a variety in the southeastern US, but other sources indicate that's wrong. Misinformation in Wikipedia--perish the thought! ;) Anyway, this is probably Y. harrimaniae , based on its location. It's probably not blue yucca ( Y. rigida ), despite the color, because it has no stem. Yuccas belong to the same family as agave, but bloom more than once.

With a little cholla for variety! Off the Fish Creek Valley road, very near the California-Nevada line. Looking east. The story is that Joshua trees got their name because Mormon emigrants thought they looked like the prophet Joshua beckoning them onward.

Arrow Canyon area, southern Nevada, USA. Probably the Mojave yucca, Yucca schidigera .
