| Yes, Jerry ,"natural selection" has a definite role. If it was a "toughie", it lasted ,growing in an old vacant lot, while, if it was on the "tender' side, the best care, in the best garden couldn't keep it alive. But also, I think, (and here some of the Hybridizers on the site could chime in), those "old" varieties were "closer", genetically to the collected species iris that started it all ( that had lasted, and been in fact developed and shaped, through that natural selection!), while the more "modern " cultivars , being line bred, in lots of cases, start losing some of their "toughness" , on the road to more frills, and fancy color combos. I know that during the "pollen daubing "process, they try to "breed back", occasionally, to a similar ,but different, bloodline, to encourage "hybrid vigor", but the fact remains that they are farther from that naturally selected, species iris , that Mother Nature, and Father Time had developed, over countless years....Arlyn |
