Occurrence. Catkin-bearing plants include many trees or shrubs such as birch, willow, hickory, sweet chestnut, and sweetfern (Comptonia). In many of these plants, only the male flowers form catkins, and the female flowers are single (hazel, oak), a cone (alder), or other types (mulberry).

How do pinecones mate?

Pollen is carried from the male cones of one tree to the female cones of another by wind currents. Thus, completing the first step of reproduction. Step 2 – Once the female cones have been pollinated, they will produce fertile seeds within the closed cone. It takes about two years for this step to complete itself.

What is special about pine trees?

Pine trees are considered evergreens because they keep their needles for approximately 2 years. When old needles falls, new needles quickly take their place. Pine tree needles can range in length from 1 inch to 11 inches. Both male and female pine trees produce woody cones.
