Can someone explain the difference? Our builder gave us 3 trees when we built and all 3 were supposed to be red oaks (they wouldn't give us Monterrey Oaks and we have a ton of Live Oaks native on our lot). 2 of them look alike, white bark... the 3rd has darker bark. This was around Thanksgiving. When they started sprouting leaves they all 3 looked alike in the leaves. Now though the one with the dark bark has much darker green leaves than the other 2. But the shapes are identical. Is this a different tree?
