When looking through a local nursery, what do I come across, but 2 2.5" caliper B&B Acer mandschuricum. One tree is about 15'/5m, and the other 20'/6.5m in heights. Very upright trees that look like they are headed to much larger. Both look healthy. First thought is that it's mis-labeled, but the leaves are just emerging, and they are definitely trifloriate as would be expected. Expensive, but not any more than other trees of the caliper. Just wish I had a place to put one........... Anybody know where a mature specimen is, and how big they really get? Culture, etc?
