La's, Ji's, and SIB's are all ' iris'....so they count, as do the "bulb sorts" whether they be reliculatae, Dutch, or English ( if you buy a dozen Dutch bulbs, you wouldn't count it as a 'dozen", just as 'one cultivar", though !)
I'm glad that we're not 'required' to divulge how many iris PLANTS we have.....as many of my cultivars grow in *several* places, around the property
! It's rather *strange*, that when I dig a plant, for division, or "sharing", I find it VERY hard to discard the "crumbs".....those spent mothers, disfigured, or super small daughters, or even the ones shot full of borer holes, and affected by rot..........I just can't seem to help myself, and pretty soon......there are two, or three (or maybe more
)places where it's growing !
