Allergies and pollens

If anyone can tell me what the relationship is between the following plants I would be most grateful.

  • Laurels
  • Pieris
  • Honeysuckle

I find certain plants when they bloom much more aggravating. I didn’t know the name of the first two plants, but I see them around Eugene quite a bit. So I stopped by Jerry’s to find out what their names were. Just around this time of the year Laurels and Pieris are blooming and it drives me crazy. My lymphatic system swells and the breathing becomes problematic.
