A vigorous weed that has a large number of cultivated varieties grown for the herbaceous border. I have grown a great many of them, and they
all look more or less like this (which is a seedling that came up in the greenhouse foundations). Some err more towards pink, and some
drift into lilac, but not so far that you would not recognise them!
It is worth noting that this is a good picture of a good specimen on a good day!
