How is this possible? Because seeds are so tiny and light that a light breeze can pick them up and carry them away. Sweet birches are also self-pollinating, so they can repopulate even if there is a lack of pollinators in an area. Sweet birches are true thrivers and survivors.
What do Look Like?

Once fruit matures in the fall they are composed of many tiny winged seeds that stay put in between bracts. Once the wind blows, so do the small seeds.
For sweet birches, seed production is the most prolific during the ages of 40-200 years old, but it sometimes occurs in trees that are under 15. Since so many seeds are produced and they are so light, the wind carries them to far-reaching places. Without hard shells, many of them get eaten, but many of them also have the opportunity to germinate quite quickly. This is why they are referred to as pioneer species.
Where do Grow?
Of many of the varieties of trees, the is far more tolerant of changing and more drastic climates. They grow in regions that aren’t too hot or cold (usually mesic forests) and that doesn’t get too wet or too dry.

- northern Georgia
- the southern Appalachian Mountains
- southwestern Ontario (Canada)
- monoecious (both and female flowers)
- 30-35 meters tall
- 0.5-1 meter of trunk diameter
- ovate leaves
