The north gate's steps lead you back to the upper garden areas. The gate is in the center - a kiwi is growing across it. In the lower left you can see a grapefruit in flower, and the red flowers from the rose gate just past it. Across the path are two navel oranges in flower. Again This is the north gate from the other side.
Roses are on the left growing between the north and west gates.
The Kiwi is a little easier to see on top of the gate. The red flowers are the rose gate again. The bush with the little pink flowers on the right is a citronella-scented geranium. Here's a shot from the north gate over the mint garden looking out to the kid's playhouse near the oaks. That's kiwi wrapping the pole in the foreground, and a vining geranium below it.
