Symmetry, vigor, and colorful foliage have earned Nuttall Oak (Quercus nuttallii) a place among the most frequently specified oak trees. It is similar to Shumard and Scarlet Oaks in habit and leaf, but Nuttall Oak always drops its leaves clean in the fall. Quercus nuttallii can have nice long-lasting fall color. Because it's a bottomland species, it's tolerant of adverse soil conditions and planting sites. Another excellent urban oak (also look at Q. bicolor, Q. lyrata, Q. phellos).
