Acer davidii ssp. grosseri - Stripebarked Maple Family - Aceraceae Size - Slow to medium rate of growth to about 20' to 25' with a comparable spread. I feel its top size in the South will be in the 15' to 20' range. Similiar in foliage and habit, to A. davidii. Foliage - Medium green, Yellow Fall color. Flower/Fruit/Seed - Interesting in that like A. davidii, this tree also produces separate male and female branches which can produce flowers of the opposite sex in alternate or successive random years. Bark- Green to gray-green on older wood, with very conspicuous white striping. Highly ornamental. Individual branches have prominent striping, especially on younger wood. Pests and Diseases - None noticed, would seem to perform best if given some afternoon protection in the hottest part of the day in summer. Landscape Use - A tree which can be integrated in to the residential yard as a focal tree or used in a planting as a specimen. Would work well in the small commercial site as well. Tolerates full sun to part shade. It's bark is the greatest asset, especially in winter, and the tree should be placed in a location in which it can be seen for this reason. Normally seen only in arboreta and other collections. Rarely, if ever, available in the trade, except from specialty growers. Performance - 7 - Some trees just give you the initial impression that they won't cut it, and then fool you. Hardy to Zone 5. October - 1998 - Since initial planting in Spring of 97 this tree has shown no problems related to heat, in fact it has done quite well, approximately doubling it's caliper in the last year and a half. It has gone from a 1" caliper tree in 97 to approximately 2 to 2 1/2 inch caliper. Growth range has been approximately 1 foot or slightly more. May - 2002 - Caliper approximately 4.5 inches. In May of 2003, I have noticed the possibility of some canker problems. I don't attribute this to heat, but possibly other stresses such as too much moisture, and/or mulch piling up against the trunk. Although it has affected the tree, I don't think we will lose it. The tree is in an area which can be prone to short term flooding, and evidently this is what is happening. In a typical location, I think the tree would do fine.
