Iris coccina

I contacted Angelo. I was hoping he'd reply first, but maybe he already
went to bed. :-)

Here was his reply: "It's Iris collina, which is considered a synonymous
of Iris sintenisii. This species is found in Southern Italy and it's not
well understood if it's the same species of the Balkans or a valid
subspecies. Probably Dell couldn't read my label. It's Iris collina, not
coccina."

So it's a type of Spuria iris.

Here's some more from the Googles:
