The Anza-Borrego Desert is 600,000 acres of stark, hot, harsh beauty. It is quiet. Very, very quiet. Everything that lives here has adapted to the heat and lack of moisture. Many plants in the desert are "drought deciduous" meaning that they drop their leaves in times of drought and go dormant. When it rains the plants become active and new leaves emerge. This cycle may repeat itself several times throughout the year.

The south of Vancouver Island, like southern California, has a Mediterranean climate with warm, dry summers and moderate, wet winters. Many of the plants I saw in San Diego, and even the desert, were familiar to me after seeing them in Victoria region gardens.
Palm trees for example, may not be as large or as healthy as those further south, but Victoria does sport a number of them.
Plants that tolerate drought can do well in the Victoria area. The native Arbutus is an ideal tree to plant in low water exposures. Although I have never seen one in Victoria, the Smoke tree would probably do well in the garden here, too.
The Smoke tree, native to California, grows up to 11 meters tall, although it often grows as a shrub in the harsh environs of the desert. The tree has small dark green oval leaves that turn brilliant colours in the Fall. It sports showy clusters of tiny deep blue flowers in the summer.

Not surprisingly, the Smoke tree is said to indicate the presence of underground water. It has a long tap root that plunges through the poor soils seeking water deep below the parched surface.
