Ficus benjamina - Weeping Fig

All this sun must lighten up the color from that one I saw.

GT:

In full Sun the leaves are a little smaller than when grown as house plants.
The Sun doesn't lighten the leaf color. What happens is the new leaves are lighter-colored than the darker old leaves. It has a two-toned color effect on the tree. It is very common for many species of Ficus to have this two-toned color when grown outside in full sun. I'll have to post a photo of a close up of a smaller tree so you can so the what I mean. It difficult to see on these large trees.
