Bur/Burr Oak is perhaps my favourite tree - though I have to admit that I don't know much about trees at all, despite being told more than enough times. In the fall, Bur Oak leaves can turn brilliant yellow, but this fall has been short. The snow that was forecast to arrive overnight thank goodness didn't arrive, other than a few snowflakes when I was walking this morning. I'm really, really hoping that it stays away. We did have rain overnight, though, and it has been grey and gloomy all day, and it's cold. Wore a fleece jacket under my winter jacket, plus toque, long-johns and two pairs of gloves!! It might just as well be winter, LOL! "The Quercus macrocpoopa or Bur Oak, sometimes spelled Burr Oak, is a species of oak in the white oak section.... Bur oak makes an outstanding ornamental tree. It is one of the most tolerant of urban conditions of the white oaks, and is one of the fastest-growing of the group.... It withstands chinook conditions in Calgary. The leaves are 7-15 cm (3-6 in) long and 5-13 cm (2-5 in) broad, variable in shape, with a lobed margin. Most often, the basal 60% is narrower and deeply lobed, while the apical 40% is wider and has shallow lobes or large teeth. The flowers are greenish-yellow catkins, produced in the spring. The acorns are very large, 2-5 cm (0.8-2 in) long and 2-4 cm (0.8-1.5 in) broad, with a large cup that wraps much of the way around the nut, with large overlapping scales and often a fringe at the edge of the cup."
