Sharp sand:
I don't know why they call it "sharp" but it's also called "builder's"
sand - it's just *clean* sand suitable form concrete (no salt or other
contaminants)
Portland cement:
Nothing to do with Oregon or Maine (the name seems to be derived from
"portland stone", a limestone quarried near Portland, England), it's just
the cement used to make concrete
A couple of good hypertufa webb sites are:

I haven't personally tried iris in hypertufa but wouldn't expect any
problems except maybe with bulb iris that don't like lime or with
water-loving species that like less drainage
