Acer rubrum Redpointe®
Redpointe Red Maple
Native to (or naturalized in) Oregon:
- Broadleaf deciduous tree, broadly pyramidal form, dominant central leader, fast growing, 45 × 30 ft (14 × 10 m). Leaves opposite, simple, 3 major lobes and usually 2 minor lobes (i.e., 5 lobes), dark green, fall foliage is brilliant red.
- Sun, very tolerant of soils.
- Hardy to USDA Zone 5 .
- Developed by Keith S. Warren at the J. Frank Schmidt & Co. nursery, Boring, Oregon; PP16,769, July 4, 2006. The following is from the patent application by Keith Warren: "Classification: In recent years, some authors have reclassified some cultivars of Acer rubrum as the hybrid species Acer.times.freemanii. A few of the seed and pollen producing trees in the Arboretum that contributed to my seed supply could be classified by these authors as Acer.times.freemanii. There is not complete agreement on this issue among experts. My belief is that Acer rubrum and Acer.times.freemanii form a species complex with various degrees of genetic introgression. In this patent application, Acer rubrum is used in the broader, traditional sense. My new cultivar appears closest in characteristics to the species Acer rubrum and is thus classified." [Note: Acer × freemanii = A. rubrum × A. saccharinum (Red maple × Silver maple)]
