Description
- Black cottonwood (Populus trichocarpa) is the largest of the American poplars and the largest hardwood tree in western North America. Known also as balsam cottonwood, western balsam poplar, and California poplar, it grows primarily on moist sites west of the Rocky Mountains.
- Genome-wide analysis of 11 clumps of P. trichocarpa trees reveals significant genetic differences between the roots and the leaves and branches of the same tree. The variation within a specimen is as much as found between unrelated trees.[1]
