As a Landscape Architect in Texas, a constant request from clients is SHADE! Another option to planting trees is constructing an arbor. An arbor is a great focal point in the garden and can be very simple, intricate, or even an extension of architecture from the house or building. One of my favorites here in Austin is at Whole Foods outside on the plaza. The most beautiful characteristic of arbors is the way sunlight moves through them and seeing the different shade patterns that are created on the ground.
