I've been watching it for a couple weeks now. It was late turning this year. All the trees were late, but it seems the Japanese maples the slowest of the bunch. That being said, they can be quite the show offs as well.
Julian was in town to spend Thanksgiving with me last week (what a treat!). I was happy there was still a lot of color going on, so he could have a proper (or close to) east coast autumn experience. My own little maple was getting its colors on. But it wasn't until this morning...after a good rain...that the vibrancy of this tree is gloriously apparant.
It's interesting to watch at the height of color, the leaves falling with abandon in the wind...as if the tree is understanding the time to sleep is near and it's opening itself up wide, claiming a right to exist, before the little death of dormancy. "I'll be back!!" it seems to say.
