I have this lovely perennial in the garden which is a lovely plant being tall, strong and extremely long flowering. It is also attractive to bees/insects and so easy to propogate that it's untrue!
My problem is that I just can't get a proper ID on it! Frustratingly I have got it down to either a form of NEMESIA or DIASCIA VIGILIS of some sort????
If it helps it is a good 3' tall and has square hollow stems, serrated/toothed green leaves and flowers from spring through to the first frosts....
Your help would be very much appreciated....
