American Pillar Arborvitae (Thuja occidentalis 'American Pillar') Pollination Info

American Pillar Arborvitae is a male cultivar of the Thuja occidentalis species, known for its narrow columnar shape and dense foliage. Unlike female cultivars, American Pillar Arborvitae does not produce cones or seeds.

Since American Pillar Arborvitae is a male cultivar, it does not play a direct role in the pollination process. However, nearby female cultivars of Thuja occidentalis may produce cones that contain seeds. These seeds are dispersed by wind or animals and can result in new arborvitae plants.

It is recommended to plant both male and female cultivars of arborvitae in close proximity if seed production is desired. Cross-pollination between male and female plants can lead to the production of viable seeds.
