Introducing Quercus × morehus, a fascinating and distinctive hybrid tree known as Oracle Oak. Initially identified as Abram’s oak by Albert Kellogg in 1863, it was later proven to be a cross between the California black oak (Q. kelloggii) and the Interior live oak (Q. wislizeni). This unique status was first acknowledged as Oracle Oak in Willis Linn Jepson’s 1910 book, "The Silva of California".
Oracle Oak finds its distinction in the winter landscape, where its semi-evergreen, tardily-deciduous nature sets it apart. By mid-winter, an Oracle oak has usually shed many of its leaves, displaying a characteristic yellow/brown appearance. This allows it to stand out amid the parent species - the deciduous California black oak and the evergreen Interior live oak, particularly when these trees' habitats overlap. Its leaves are a striking blend of its parent species'. Combining the small leaf size of the Interior live oak and the larger leaves of the black oak, Oracle Oak presents a leaf of moderate size.
Whether you're a botanist, a nature enthusiast or an everyday admirer of unique species, the Oracle Oak is sure to captivate your attention with its distinctive charm.
