We have a very similar bush in the U.S., called Beauty Berry, in the Verbena family. Would your's be in the same family? Ours is quite a handy little bush. The berries are edible, but don't taste very good, but make a wonderful jelly. I've tried twice, I've never gotten it to jell though. Ended up with a tasty syrup. For a mosquito repellent you can rub the leaves on your skin.
