In some recent treatments of these genera Manfreda is placed within Agave, making this an interspecific Agave hyrid rather than an intergeneric. But the jury still seems to be out so we'll keep the x Mangave label for now. Whatever it's botanical name, it's still 'Bloodspot', a very appropriate name. It's probably quite hardy, but not hardy enough for us here in the Willamette Valley of Oregon. Not a big deal because it makes a very nice potted specimen.
