I think adductum is one species that (like stonei perhaps) can add really distinct qualities to it's hybrids. I have to say I prefer the coryo. hybrids over ones made with brachys/parvis as the other parent, but that's just me. The color it can impart though is rather fascinating. I look forward even more to seeing what var. anitum can produce. Then again, I'd just settle for anitum.
