Green Giant Arborvitae (Thuja plicata 'Green Giant')

Pollination Information for Green Giant Arborvitae (Thuja plicata 'Green Giant')

Green Giant Arborvitae, also known by its botanical name Thuja plicata 'Green Giant', is a popular evergreen tree prized for its fast growth, dense foliage, and tall, columnar shape. It is an excellent choice for creating privacy hedges or windbreaks in landscaping.

Pollination:

Green Giant Arborvitae is a monoecious plant, meaning it has separate male and female reproductive organs on the same tree. The male cones (pollen cones) produce pollen, while the female cones (seed cones) produce seeds. The tree is wind-pollinated, with the pollen being carried by the wind to fertilize the female cones.

Pollination Period:

The pollination period for Green Giant Arborvitae typically occurs in the spring when the tree is actively growing and producing new foliage. The male cones release pollen into the air, which is then carried to the female cones to fertilize them.

Attracting Pollinators:

While Green Giant Arborvitae is mainly wind-pollinated, it can also benefit from the presence of pollinators such as bees, butterflies, and other insects that may inadvertently transfer pollen from one tree to another. Planting other flowering plants nearby can help attract pollinators to your garden and increase the chances of successful pollination.

Seed Production:

After successful pollination, the female cones of the Green Giant Arborvitae will develop seeds. These seeds are contained within the cones and will be dispersed by the wind when the cones mature and open. The seeds can be collected for propagation or left to naturally spread and germinate in the surrounding area.

Overall, Green Giant Arborvitae is an easy-to-grow and low-maintenance tree that will produce seeds and continue to thrive when planted in suitable growing conditions.
