It was a real surprise to discover these little red things on the tips of Yellow Birch buds. Are they flowers? I don't think so, as this birch has catkins. I'm confused and can't find documentation. No worries. I'll just watch and see what happens. Maybe they are flowers, perhaps the start of the bud, and of course, I just might have misidentified the species. Regardless, they are rather pretty little things, aren't they?
Update: 11 Jul 2009. These are the female flowers of the Hazelnut.
