Yes, but they too, benefit from a lower pH and good soil culture. Orientals as a division by themselves can be a little more fussy than Orienpets. Still, I think if you just lower your pH a little each year for the next two, three years, you'll see whatever Orientals you do have left will spruce back up and become progressively more vigorous.
I, myself, prefer Orienpets because there are so many cultivar choices commercially available out there with such a wide variety of lovable colors and fragrances--and for the most part, pretty hardy.
