Pollination Information for Whitespire Birch Trees

Whitespire Birch trees (Betula populifolia 'Whitespire') are deciduous trees that require pollination in order to produce seeds and continue their growth. The pollination process of Whitespire Birches is carried out by the wind.

The trees produce small and inconspicuous flowers in the spring. These flowers are typically arranged in groups of two to three and are called catkins. The male catkins produce pollen, which is carried by the wind to the female catkins on neighboring trees.

Once pollination occurs, the female catkins develop into small, winged seeds known as samaras. These seeds are typically dispersed by the wind and can travel long distances before they eventually settle and germinate into new trees.

It is important to note that Whitespire Birch trees are not self-fertile and require cross-pollination with other birch trees in order to produce seeds. Therefore, it is recommended to plant two or more Whitespire Birch trees within close proximity to one another to promote successful pollination.
