Recently we spotted an extended thicket (multiple acres) of what struck us as bamboo crossed with birch. The trees were clumped very densely together and had grown to a rather uniform height of 6-10 feet. This was around 3 miles west of Walker, MN near the Shingobee section of Chippewa National Forest. Here are a few photos of these trees at different scales, which we’re hoping you could identify for us (ignore the few taller species thrown in). Would this species grow well in Minneapolis?
