Keeping this in view, do all oaks have catkins?
Oak Flowers. Oak trees have male flowers on one part of their branch, and female flowers on another part of the same branch. When a plant bears both male and female flowers it's said to monoecious. Once the stamens have released their pollen into the air, the entire catkin will fall from the tree.
