The term 'Poplar Variety' refers to two different species of trees, the ABELE (Populus alba) and the ASPEN (Populus tremula). Both species are deciduous trees native to Europe and Asia, and are widely cultivated for their timber and ornamental value. The ABELE is a medium-sized tree with a pyramidal crown and white bark, while the ASPEN is a small to medium-sized tree with a rounded crown and greyish-white bark. Both species are fast-growing and tolerant of a wide range of soil types and climates.
