Connections!
* Black birch is also called Cherry Birch and Mahogany Birch, because
of its hard, reddish bark.
* The wintergreen smell of broken twigs comes from the black
birch's sap, which has been used to make a commercial extract
called Oil of Wintergreen. A wintergreen tea can be made by covering
cut up twigs with boiling sap and allowing the mixture to steep.
Fermented sap has been made into birch beer.
* Black birch wood is hard and rich in color, and is been popular
with furniture makers. A certain wavy type of the wood is very
valuable.
* Black birch is most common in areas that were recently disturbed
by fire or logging. Its small seeds disperse very easily. |
