What Makes Them Bloom?
Joshua trees are in mass bloom in the Mojave desert this year. What makes these crazy trees bloom? Your smartass answers are always welcome, and would be as good a guess as anyone’s. But conventional wisdom, and Wikipedia, claim that rainfall and a hard freeze is required.
It seems the wise, Wikipedia-types weren’t around eight years ago. That’s when a drought brought zero rain to our desert over the winter. And yet nearly all the Joshua trees bloomed. During normal years you’ll see a smattering of blooms–a tree here, a tree there, but with most barren of blooms. And some years, hardly no trees bloom at all.
However in 2008, botanists were baffled to see almost every Joshua tree in rare, full bloom. And this during one of our driest winters on record. So what caused the mass bloom? Scientists came out from all over to study the phenomenon, but never figured it out. They’re still scratching their heads.
The Joshua tree got its name from Mormon settlers who thought it resembled the biblical Joshua lifting his arms in the air in praise of God. I think they should be renamed the “Seuss Tree” since they look kind of like trees found in Dr. Seuss books. The botanical name is Yucca brevifolia. This means yucca with short foliage. Joshua trees have short, spiky leaves, as opposed to most yuccas with much longer spikes. Yep, those spikes are technically leaves.
Joshua trees can live up to a thousand years. They only grow in the Mojave desert of California, Arizona, Nevada, and Utah. Some say they also grow in Israel, but this is a myth. The only Joshua that grew in Israel was the biblical Joshua, who never saw a Joshua tree in his life.
Today you can find tens of thousands of these trees growing in Joshua Tree National Park, California. But global warming is causing it to depopulate its southern range. Botanists fear that by the end of this century it will no longer be found in its eponymous park.
The Joshua is a strange, grand, majestic tree to behold. I feel kind of sorry for those who’ll live here a century from now. This desert will look rather bland without them.
