This tree is growing in Sunnyvale, CA. I'd love to know what kind it is.
Please name this tree.
Triadica sebifera ? Inflorescence would confirm, I have seen similar plant near Fremont, CA
It's not a Cottonwood tree because those have leaves that are white underneath. And I don't think it's a Triadica sebifera (Chinese Tallow Tree or Popcorn Tree) because I have never seen any inflorescence and the leaves are heavier and a lighter green. Good guess though because the leaves are shaped almost the same.
It would be helpful to have better close-up pics of the leaves and buds.
More and better photos will always help in getting a quick identification.
