Acer rubrum 'October Glory' (October Glory Red Maple)


Michael's Opinion

I forgot that I had planted several small trees on the college grounds until one day driving to work I saw this clear-red blaze on the edge of the parking lot. When I went to investigate I was reminded of 'October Glory': truly magnificent.
