Brown Landscape with Punches of Green
I cannot seem to get over the difference in landscape between the mid-western and southwestern parts of the United States. Although both are beautiful in their own ways, I have to say that I prefer green over brown.
Palm Springs, Palm Desert, Yucca Valley, as well as the surrounding areas are nothing short of arid. Sand makes up any soil, and on the surface appears that is all there is. This is expected on a beach, but inland? Yes, here it is expected, as the counties of San Bernardino and Riverside encompass parts of the Mojave and Colorado Deserts. Sand is expected in deserts!
Geography and Topography
This resort area is ringed by mountains, with flat valleys in between. The San Bernardino Mountains are to the north, with the Little San Bernardino Mountains to the east, the Santa Rosa Mountains to the South and the San Jacinto Mountains are to the west. The infamous San Andreas fault runs through the area as well. As you can imagine, I found myself in a different world than the limestone bluffs, verdant coulees, and what’s left of our open prairies in the midwest. With different topography, geography, climate, and soil comes different flora and fauna.
California Palm Trees
Having always been enamored of the desert, I took a guided tour through Joshua Tree National Park. But, the park flora will be fodder for another post. First, we started out in an air-conditioned van and visited an oasis of California Palms (Botanical name: Washingtonia filifera) growing on the San Andreas Fault line. These palms are not what you would see in Florida or the Carolinas. They are indigenous to the Southwest United States and spring up where water bubbles up from a crack in the ground (fault-line). Thus, the area is called an oasis. Most oases support groves of trees, which are fed by the available water reaching the ground surface through the faults. If the fault moves in such a way that it closes, the water will cease to be available. We visited the palms in a place exactly like what is described. I found them fascinating with the shaggy skirt of dead leaves that extends naturally from the top of the tree to the ground. Native Americans had many uses for the California palm oases, as they supported enough necessary elements of life to enable the creation of a village or home base. Miners and other early settlers also found the palm oases invaluable.

The palms thrive in the dry heat with a ready-made natural water source feeding their need. According to our tour guide, the area around Palm Springs is fed by the second largest aquifer in the United States! You would not guess this by just looking around!
The California Palms are also propagated for decorative uses. Often the shag will be trimmed off for a more aesthetic appearance such as these trees (shown below) in downtown Palm Springs.
The California Palm was just one example of flora that was new to me during my visit to southern California. It’s obvious that they can thrive in the intense heat of the desert, given a little water from a crack in the earth’s crust!
Do you like palm trees or not? Why?
