I haven't grown the Iholena, so I can't tell you and I don't find that info in reference to the Iholena. However, your picture does not match that of an Iholena or its variances. The pstem should have some streaks of purple and pink; and the cigar & young leafs should have a bronze tint on the underside. ... I don't see any of those in your picture. I think you may have an Orinoco there.
