The speaker asked us to identify the plants growing near our house. We have three street trees in front of our house. I cut the concrete and dug the holes for each of them, I’d say at least twelve years ago.

Left:
Genus: Zelkova
Species: Zelkova Serrata
Cultivar: ?
Common name: Japanese elm?

Center:
Genus: Acer
Species: Acer Griseum
Cultivar: ?
Common name: Paperbark Maple Tree.

Right:
Genus: Quercus
Species? That’s a good question
Cultivar:
common name: Some sort of oak tree. Scarlet? Pin? Red? (coccinea, palustris, rubra)

Then I went to OpenTreeMap for Philly and added these three. I’ll have to go do some measurements later.
