I was out working in the garden this morning and decided to go check out Mr. Pine. It is covered with these:
Each of these yellow shoots is where the new branch growth is. And that yellow stuff -- it's pollen. I wish I could have snapped a good picture of what happens if you brush up against or shake a branch. It's a yellow cloud of -- pollen. I haven't been too bothered by allergies yet this year - just the last couple of days. Maybe it's Mr. Pine.
