A poplar with silvery-white leaf undersides; its male catkins give early pollen in March-April, with no nectar. Bud resin adds to propolis, though less than black poplar.
White poplar is a poplar that grows along rivers from southern and central Europe to Central Asia and North Africa, even on salty and sandy soils; it is common in Turkey. The undersides of the leaves and the young shoots are covered in white felt. It is wind-pollinated and gives no nectar.
It flowers in March-April, before leaf-out. The catkins of male trees give pollen, which bees collect at the same time as willow and fruit trees.
It is not a honey source. The pollen is a secondary source that helps spring build-up.
Its buds are not as sticky with resin as those of black poplar, but bees may still visit them for propolis. It spreads strongly by root suckers and should not be planted in small spaces. On dry and salty soils it can be used as a windbreak to shelter apiaries.
