While it has a pretty flower I've always avoided it because of it's powdery mildew issues. <br /><br />The bad part about powdery mildew is that it's tough to stop once you see it. You can chemically pre-treat for it very well early in the season with a funcicide, but once it's there it's tough to stop. The best ways I've found to limit the damage after infestation begins is to thin plants out to allow more sun and airflow.Coreyhttp://www.blogger.com/profile/17294937394397021875noreply@blogger.com
