The variegated Lemonwood tree is an unusual cultivar seen in Santa Cruz county. This one shown here was a surprise to me walking in this neighborhood. There are other Lemonwood trees but this is the only variegated one. I wonder if it was a mistake, not a bad one, likely not intentional. My guess is this tree will grow about 2/3 the height of the species. You can see in this image its brighter green, and smaller.
Leaves are evergreen, simple, alternate, oblong to elliptical. 1-4" long with undulated margins, these being white rather than green.
Misidentification
If you looked quickly at the foliage you might think its a variegated ficus.
