I think that there might be some heredity involved as well - - not for the last one pictured, but for others. About a third of the other seedlings that I lost to crown rot had Alan Lane Agin as a parent, and I actually caught the cultivar itself just as the first fan started to discolor. I dug it up and tossed the affected fans and cleaned up what remained. Shortly after, however, my dormant plants were all shutting down for the season, so I won't know if I saved Alan Lane Agin until spring. One thing for sure, I won't lose any dormant plants this winter for them not having enough cold weather! The weatherman is predicting 2-5 inches of snow here over the next 36 hours! Its the first time in three years that the word "snow" has even been in the forecast.
