Poplar - The aspen (Populus tremula L.) grows to 65 feet along rivers and as a pioneer species after fire or logging. It sprouts from the base and may form clumps or thickets. The black poplar (Populus nigra L.) reaches 100 feet in sandy and gravely soil along rivers. The white poplar (Populus alba L.) is of similar size and habitat, but is more common in southern Europe. The white and black poplars are cultivated in North America (the "Lombardy poplar" is a form of black poplar), and several native poplars are similar in habitat and appearance. The North American aspen (P. tremuloides) is very similar to the European aspen. Poplars are members of the Willow family (Salicaceae). Curtis Clark |
