I've been intending to post this one and ask for help for quite a while. It's an almost powder-blue color (I'm partial to blue succulents...*sigh* ok, I admit, I partial to several other colors, too), about 18"/45cm or so across, has pinkish-brown teeth on the leaf edges, plus a few teeth in a sparse row on the underside of each leaf, near the tips. I could grow old waiting to picture it in bloom, so I'll just ask now:

Does anyone have a clue about this Aloe's identity? I'd appreciate any help! Thanks
