Abstract

A new variety of Quercus robur var. fastigiata, particularly characterized by its broad columnar body formation for about one-half of its height with the upper portion tapering inwardly in a fastigiate manner and having closely spaced, narrow branching requiring very little trimming to keep a six to one fastigate growth habit, and being thickly clothed with dark green obovate leaves which have about three to seven rounded lobes on each side, thereby providing a very unusual and excellent form for use as a landscape tree; this new English oak cultivar being especially distinguished by its resistance to mildew on its foliage.
