While we were passing through Birr on the way home, we stopped at Birr Castle.This is actually Patrick in the middle of a bamboo grove - actually it was more like a tunnel of bamboo, really. About 40 feet long, the bamboo had grown on both sides of the path and met at the top.
Although this would actually be an interesting technique in a garden, my childhood experience of bamboo is that's it's more invasive than mint. I think my father tried for 4 years to get rid of some stuff - not sure what carcinogenic chemical he finally used to get rid of it.
