甜香杨梅

Bog myrtle is a sweet-smelling decorative bush. It makes a terrific insect repellent, well known by campers who use it to keep their tent free of irritating insects. During the Middle Ages, bog myrtle was used for flavoring beer, only loosing this function when hops became widely available. The plant has a whole list of useful applications, including a remedy for stomach aches and acne. Bog myrtle bushes are either male or female, which you can see by the different catkins. Males are long and females are compact. It's not unusual for a bush to switch to the other sex the following year.
