Trees of Colorado: The Austrian Pine
While its name may evoke visions of the von Trapps singing their way through the Alps, the Austrian pine is most widespread in the higher regions of the Adriatic coast and Turkey. As for Austria, it’s found in the westernmost Alps near the Swiss and Italian borders. A western subspecies also grows in the mountain regions of Spain and Morocco.
Also known as the black pine, it was widely imported to England and North America. An extremely rugged tree, Austrian pines were widely planted as windbreaks in the Dust Bowl areas of the 1930s where they continue to be popular as landscape trees as well. It has naturalized in southern parts of the US Midwest.
Trees of Colorado: The Autumn Blaze Maple
Are you envious of the beautiful fall colors of New England? Or do you just want a shade tree that will turn heads with a blaze of color when summer turns to fall? Then the Autumn Blaze Maple is the tree for you.
Sheath Your Shears till After the Snow Flies
Fall is a hard season to predict along Colorado’s Front Range. The earliest freeze in Denver was on September 8, 1962, but just 18 years earlier it didn’t come till November 15. In 1961 it snowed on Labor Day! The National Weather Service pegs October 7 as the average first freeze date, but if you’ve lived in Colorado for any length of time, you know there’s nothing “average” about the weather here. Even the experts can only nail down the first frost to 60-day window.
