And then there was pollen!

If you've ever had your car covered with yellow pollen, this is an example of one of the culprit trees. It's a pine tree, not sure what species. 


I noticed this morning that all of the branches seemed to be tipped in yellow. All of the yellow color on the branches is pine pollen. I'm curious about how long it will take before the tree turns back to its normal color! The good thing for allergy sufferers is that pine pollen has such a large particle size that it doesn't usually cause allergic reactions. Pine trees do get a lot of blame for allergies in the spring even though it's not deserved. Lots of other "late spring pollinators" happen to pollinate at the same time as pine. Maple, oak, and ash are just a few examples, but you won't see the pollen from these trees. They have a much smaller particle size. In other words, it's the pollen that you can't see that causes allergies, not the ones that you can see!
