Recently, another discussion on the AHS Daylily Email Robin spurred a member to take charge. Some daylilies start to get twisted or deformed shoots as they begin to grow. They seem to recover as the weather warms, but may retain some leaves that are deformed. Sue has put up several excellent pictures on her site . No one really knows whether it affects evergreens or dormant.
Some people think it is climate induced from cold and wet spring weather.
If you think you have plants with this disorder,there is a form on this site for you to fill out. Check the pictures first to see if your plants symptoms match. Maybe we can get an answer to this before it becomes more than a nuisance. As the weather improves, most plants grow in a normal way. Some do not bloom as well and foilage may be stunted.
