Pollination Info for Green Giant Arborvitae (Thuja x 'Green Giant')

Green Giant Arborvitae (Thuja x 'Green Giant') is a hybrid cross between Thuja plicata and Thuja standishii. These trees are considered monoecious, meaning they have both male and female reproductive structures on the same plant.

The male cones of Green Giant Arborvitae produce pollen, which is wind-dispersed to fertilize the female cones. The female cones then develop seeds that are dispersed by wind or animals to propagate the species.

Green Giant Arborvitae typically begins to produce cones and pollen when they reach maturity, usually around 10-15 years of age. The timing of pollination can vary depending on environmental conditions and individual tree health.

It is important to note that while Green Giant Arborvitae is capable of self-pollination, cross-pollination with other trees of the same species can result in increased genetic diversity and potentially healthier offspring.

Overall, understanding the pollination process of Green Giant Arborvitae can help in ensuring successful reproduction and maintaining healthy populations of these beautiful trees.
