The Joshua tree


                  The Joshua tree is the only tree that grows in California's Mojave Desert

Today we enjoy this yucca for its grotesque appearance, a surprising sight in the landscape of biological interest. The Joshua tree’s life cycle begins with the rare germination of a seed, its survival dependent upon well-timed rains. Look for sprouts growing up from within the protective branches of a shrub. Young sprouts may grow quickly in the first five years, then slow down considerably thereafter. The tallest Joshua trees in the park loom a whopping forty-plus feet high, a grand presence in the desert. Judging the age of a Joshua tree is challenging: these “trees” do not have growth rings like you would find in an oak or pine. You can make a rough estimate based on height, as Joshua trees grow at rates of one-half inch to three inches per year. Some researchers think an average lifespan for a Joshua tree is about 150 years, but some of our largest trees may be much older than that.

Thank you for thinking of Louis Dean....he is turning the corner this afternoon and beginning to feel better! Glad I brought him to the hospital when I did!

Nice photo! Isn't it amazing that something can grow with so little water? And live so long, too!

We lived in Victorville, CA for about 7 years. We watched the growth of the Joshua tree over the years. So impressive.
