This is correct. We have found 2 viruses in C. kotschyanus. Iris Severe Virus & Cucumber Mosaic Virus. Moreover I have constantly complainig about viruses to the supplyers, they ignored me. There is usually 1 grower for rarer items and the inspections are in spring so the inspectors won't see any sign of infection. And the severely infected plants won't flower. I've bought 7/8 size bulbs and 1 have flowered from the 20 or so from the infected. I also bought 5 bulbs from seed grown 3,5/+ size and all have flowered most of them more flowers from a shoot. While I was working in Holland I saw that they do not really care (most of them!) about plant health, they live from the money after selling so they sell, everything. One of the grower's association started a campaign to let growers and people know that plants are living, so they have to treat them like living things. Jim is correct, most commercial stock are infected with viruses. I saw Paeonias in Holland and most of them were infected. Especially the Itoh-hybrids. Even tulips in Keukenhof were infected with viruses and they don't even cared about it to pull the bad ones out. And customers don't see the infection if the plants are dormant. And the people of the street does not realize if the plants are sick. So you can still raise plants from seed or buy tissue cultured plugs whose are cleand from viruses. Of course the latter are much-much more expensive. This topic is my favourite and I could write several pages what I have seen but this is a public list... Bye, Jan, Z5a, Hungary
