Our RHS White Poplar (Populus alba) cell grown plants are extracted from their cells prior to despatch and are wrapped in protective packaging to ensure the root plug stays moist. The plants come with their root systems intact, whereas bare root plants can lose the fine feeding roots and root hairs when they are lifted. This means that cell grown plants can become more quickly established than bare root. Another advantage of cell grown White Poplar is that it can be planted into warm soils when roots are active, outside the dormant period. As long as the roots are kept moist, cell grown plants can be planted throughout the year.
The White Poplar (Populus alba) is a medium-sized deciduous hedge, growing to heights of up to 16-27 m (rarely more), with a trunk up to 1 m diameter and a broad rounded crown. The bark is smooth and greenish-white to greyish-white with characteristic diamond-shaped dark marks on young trees. The young shoots are covered with whitish-grey down, including the small buds. The leaves are 4-15 cm long, five-lobed, with a thick covering of white scurfy down on both sides but thicker underneath; this layer wears off the upper side but not the lower, which stays white until autumn leaf fall.
