"Let me be by myself in the evenin' breeze
And listen to the murmur of the cottonwood trees"
"Don't Fence Me In" by Robert Fletcher and Cole Porter.
This time of year, the Fremont Cottonwoods put on a vivid show of color. Right now you can find them along the Santa Clara River, glowing bright yellow in the morning sunshine. Soon the leaves will fall and the tree will go dormant, waiting until the early spring to flower again and produce those cottony catkins.
In order to thrive, these trees need a steady supply of water. Their root systems can go 10-16 feet deep in search of water. That's why we find them growing in wash of the Santa Clara River. Even when the wash looks dry, there is water available beneath the surface.
On a hot day, the shade from these trees provides a cool and restful oasis. And the leaves flutter in even the gentlest breeze. That's because their "petiole ", the stalk that attaches the leaf to the stem, is flattened rather than cylindrical. To visualize this, imagine flapping a pencil. It remains rigid and does not bend. Now imagine flapping a piece of paper. It's much more flexible.
A closer view of the leaves. Note the long petioles (leafstems).
If you listen carefully, you may hear more than just the murmuring of leaves. These 100-foot tall trees provide nesting sites for red-tailed hawks. And because the wood is relatively soft and weak, the heavy branches often break off, providing cavities for cavity-nesting birds like woodpeckers. So you may hear also hear the scree  of a hawk or the rat-a-tat pecking  of an acorn woodpecker.
But here's where I disagree with the songwriter - beauty like this was meant to be shared. So I encourage you to invite a friend and take a walk along the paseos  bordering the Santa Clara River.
