Checklist of Cultivated Maples III. Acer Platanoides L.

Norway maple (Acer platanoides L.) is the most abundant and widespread native maple in Europe, ranging from southern Sweden and Norway to Spain, Italy, and Greece, and west to Siberia — from about 65°N. Lat. to 35°N. Lat. (7). Interestingly, it is not native to the Netherlands or Great Britain.

Norway maple was introduced into North America in colonial times and currently is the most widely planted maple on the streets of urban areas of eastern United States (2). Unfortunately, little is known about the exact geographic origins of the Norway maples planted in North America, but it is unlikely that any significant introductions came from southern Europe. Future introductions from this area might further extend the utilization of Norway maple.

Recognition and selection of variations in Norway maple, chiefly in regard to leaf shape and color, seemed to reach a peak in the late 1800’s. The first cultivars grown in the United States were selected in Europe and many of these are still popular. Over the past 30 years a number of American selections have been introduced, based largely on crown form and growth habit. Some of these cultivars were also chosen, albeit inadvertently, for adaptability to difficult urban site conditions, since some were selected as older, planted trees growing in such areas. However, selection of a cultivar to be propagated vegetatively on rootstocks of unknown origin and adaptability does not insure the uniformity of “survival” characteristics that might be expected if the tree were on its own root system or a rootstock selected for superior urban performance (4).

One of the difficulties in evaluating the older European literature is determining which of the many variants described would satisfy our modern concept of “cultivar” according to the International Code of Nomenclature for Cultivated Plants (1). For guidance in these determinations, as well as assistance in cultivar synonomy, we are indebted to Murray (3).

The U.S. National Arboretum assumed the temporary International Registration Authority for unassigned plant genera, including most landscape trees, on January 1, 1981. We have also accepted the responsibility to provide suitable checklists of cultivars of important landscape tree species and genera. The first two checklists in this series (5, 6) were devoted to red maple (Acer rubrum L.) and sugar maple (Acer saccharum Marshall).

We have attempted to make these checklists as complete and accurate as possible by enlisting the aid of numerous reviewers, including all nurserymen and others involved in the introduction of the more recent cultivars. Still, we recognize that there may still be errors or omissions and ask any readers with new information or verified corrections to contact the senior author at the U.S. National Arboretum, Washington, D.C., 20002. We also urge all who may contemplate the introduction of a new tree cultivar to contact Dr. T.R. Dudley at the U.S. National Arboretum for registration applications and other information.

As before, VALID CULTIVAR names are shown in boldface capitals and INVALID CULTIVAR names are shown in lightface capitals.
