"This oak is very nearly hardy, and it retains its leaves here until January or February; in fact, it never loses them until we have a sharp nip of frost. Its flexible shoots, graceful habit, and diversified foliage make it a desirable addition to collections of hardy trees. It is sometimes called in catalogues Q. agnostifolia." It is however just possible that this refers to Quercus Robur heterophylla, quite another thing and which is already in the"Fairmount collection".
