Horrific spring, fall and winter blackspot! The only time this plant was clean in my yard was during high summer, when there isn't much disease around due to the high heat. Note: At the time, my garden was sprayed regularly with fungicides.
Culled Fall 2015- one of the worst blackspot offenders ever in my garden. (I live a few blocks from the bay, so I'm sure that has something to do with it.)
