Can anyone help identify this Yucca for me. I am thinking it might possibly be either a Spanish Dagger or Spanish Bayonet. Thanks

It looks like the stuff we called Spanish Bayonet when I lived in Modesto but I'm no expert.

Doubtful. Are you in California?
It looks like the common Y. gigantea (usually called Y. elephantipes).

Looks like Yucca gloriosa to me. There are 2 or 3 species in the ballpark which are not all that different.

Database links for the 2 suggested names. I'm leaning more toward the more commonly grown one here in Calif., Y. gigantea.
Spineless Yucca (Yucca gigantea)
Spanish Dagger (Yucca gloriosa)

Differences between Y. gloriosa and Y. gigantea, according to my reference book (Irish & Irish):

Y. gigantea has longer leaves (up to 4 feet long, vs. 1-2 feet long) which are darker green, often glossy or shiny (which gloriosa's are not). On gigantea the leaves are often lax (sideways or downward, not so much erect). Y. gigantea is larger overall, with a bigger inflorescence containing smaller, more numerous flowers.

Y. gloriosa is much more common here.

Thank you. Yes, I am in in the Los Angeles region-San Fernando Valley

The leaves on mine look pretty dull to to me. I don't see any gloss or shine.

Would the identification be easier if I post again once it flowers?

More visual information certainly wouldn't hurt, but I claim no particular expertise here.

According to my other reference on the genus (Thiede) the inflorescence of gloriosa should different, with the flowers starting well over the leaf tips. In contrast, only the top 1/4 (or so) of the inflorescence is supposed to extend beyond the top of the leaves on the other species.

Looks like what I see everywhere in LA - gigantea.
Leaves look like that here with a mix of stiffer and floppier leaves. I have never seen one with glossy leaves and I have been selling them for 30 years. In my experience Y. gloriosa always has a sharper harder tip compared to gigantea.
Flowers will tell the tale.

Thank you everyone for helping me with the identification. I will do a new post once it flowers.
