Yucca or Furcraea or Beschorneria?

[jam]

What do you reckon this is? The leaves are blue green with white/yellowish margins with miniature serration (like Y. thompsoniana), with sand paper feel underside (like Y. rigida or arizonica, maybe a tad more).

Or Nolina?

Yucca. As to species: It reminds me of my 2 Yucca queretaroensis hybrids with Yucca filifera. The non-hybrid plants I grow are more blue-green, but they are also variable.

Thanks, Tom. Yes, I've also concluded it is a yucca. I was thinking it could be rigida or thompsoniana. It's very blue and waxy although some pictures are showing otherwise. I've read a lot about some Yucca queretaroensis seeds ending up being queretaroensis x filifera cross, including your article about the trip to east central MX with Brian and Jeff, but these were available only once and quite some time ago therefore I think if my plant was this particular hybrid, it would be bigger by now.
