Black maples are quite widespread in the midwest: I have seen hillsides covered with them in Missouri. They are considerably more heat and tolerant than Sugar Maples for us in Colorado: we have trouble growing Acer saccharum in Denver, but we have some MASSIVE Acer nigrum: one in particular is nearly 80' tall and has immense trunk girth. You can catch a glimpse of its foliage at this URL: http://www.homeandgardenmag.com/trees-to-try/
Acer nigrum 'Greencolumn' is on the short list of trees recommended to be planted on parking strips in the City of Denver. America has got an unbelievable number of outstanding, little known trees. ----- Original Message ----- From: "Barbara vanachterberg" <[email protected]> To: "the Electronic Rock Garden Society Alpine-L; postings copyright by authors." <[email protected]> Sent: Friday, February 18, 2011 4:24:11 PM Subject: Re: [Alpine-l] Spring is just around the corner Very interesting. I had never heard of black maple. It seems to have a more midwestern distribution than sugar maple, which doesn't thrive in warmer climates. I wonder if sugar maple (my favorite tree) will be able to cope with global warming.
