Roots that hold
through the heat
As summer temperatures rise across the foothills, the trees at Morgan Oaks are doing what they do best — drawing deep on root systems that have been growing quietly for years.
The Blue Oaks, with their distinctive pale
gray-blue leaves and tolerance for dry, rocky soil, are particularly well-suited to California's long summers. Their smaller, leathery leaves reduce water loss while their deep root networks tap into moisture far below the surface. Valley Oaks, by contrast, seek out deeper soils along seasonal drainages — their grand, spreading canopies offering the broadest shade on a hot afternoon.
Walking the preserve this month, you may notice how the landscape breathes differently under each
species. We invite you to slow down, look up, and take note of which oak shades the site you're visiting. If you're not sure which is which, our team would love to walk you through it.
Quick guide: Blue Oak — smaller, blue-gray leaves, rocky upland slopes. Valley Oak — larger, deeply lobed leaves, broader trunk, valley floors and gentle slopes.
