Hi John , Jane and all, I though I might add my experiences with Colchicum luteum - I obtained seed from Kohli & Co, Kashmir, India about 12 years ago and had great germination (as well as some Roscoea and Iris species) - I was so pleased with the results I ordered again but unfortunately the second lot of seed never arrived. I was a bit over generous with them initially swapping 10 corms with a local bulb supplier for various bits and pieces , but ended up with half a dozen corms which flower regularly and increase enough to trade one or two every couple of years. It flowers in mid winter for me as it does for Lyn and Paul in Canberra. I have hand pollinated every year or two and obtained seed but have only ever raised one corm from my own seed . I dont understand why this is as other Colchicum species do so well from fresh seed. By the way John - I was quite relieved to hear your Crocus corms are not 5 inches accross !! Regards, Rob
