The plants we grow in our gardens are some of the richest and most varied in the world. But very few of them are native to this country. So where do they come from? Who brought them? How have we changed them? Irises
For sheer beauty of colour and form, the iris has few rivals.
Today Geoffrey Smith takes a look at this, one of our oldest garden flowers, and discovers its uses in an Italian industry that's stood the test of time.
