Kindred Spirit® ('Nadler') Hybrid Oak is an interspecific hybrid of the Columnar English Oak (Q. robur fastigiata) and Swamp Oak (Q. bicolor). The habit is tightly columnar, and the foliage is clean and mildew resistant. The leaves are dark green with a silver underside, turning shades of yellow and bronze in fall. Quercus x Kindred Spirit® would make an excellent tall hedge, or be an attractive architectural element when used as a specimen. Although a cross between two different species, Kindred Spirit® does produce acorns which provide food for wildlife. This is another winner from Earl Cully of Heritage Trees.
