Quercus canbyi | Stanford
A few seedlings of Q. canbyi were grown by Magic in Palo Alto, and subsequently test planted at Stanford University. In this location, they have received extreme testing. The tree shown is nearly a decade old, but only received irrigation for its first two years planted in the ground. The tree is clearly established on this dry site, and has continued to grow at a moderate pace. Q. canbyi is happiest growing with some supplemental summer irrigation, but this testing suggests real drought tolerance, which is true of almost every oak tree. The drought tolerance is built right into their genetics and structure, and even oaks that grow exclusively in wetter climates typically display a greater-than-average resistance to aridity.
