This is our first spring in the south, and although we have had pine trees before, I have never noticed the pollen. Southern pines seem to produce way more than northern species and as a result there is a film of yellow dust over cars, plants, driveways and anything else that stands still for more than 2 minutes!. This morning we have a slight breeze and that is creating what can only be called a small dust storm. Fortunately the pollen is so heavy and large that it does not cause sneezing and other spring allergy symptoms, but it sure is interesting. And there are plenty of other pollen producing trees out there to give people problems.
