"Botanical sexism is the practice of planting male trees rather than female ones, adopted in urban planning based on the idea that male trees would produce fewer pesky fruits and flowers."
"Monoecious trees have both male and female flowers on the same plant-think birch, hickory, and fir. Dioecious trees are strictly male or female."
"With dioecious trees, you need a male nearby to pollinate the female in order to see any fruit or flowers, hence what began the practice of planting only male trees."
"Scientists generally agree that our suffocating pollen count is driven by climate change, not the presence of female trees."
Botanical sexism is the practice of favoring male trees in urban planning to reduce messy fruits and flowers. This preference, theorized by allergist Tom Ogren, is linked to worsening allergy seasons. However, scientists attribute increased pollen counts primarily to climate change. Trees exhibit four primary reproductive strategies: cosexual, monoecious, dioecious, and polygamous. Monoecious trees have both male and female flowers, while dioecious trees require a male for pollination. Understanding tree reproduction challenges the notion of botanical sexism.
