 It is a large shrub now measuring approx 5ft X 5ft  Was at its best a month ago. Think the name is Phalecia or similar. 

Are you thinking of; Phacelia fimbriata ?

Thanks Tee Gee, I am not sure that it is Phacelia fimbriata as the image on Google show a different type of flower.  Mine has hundreds of tiny pink daisy like flowers.
I originally had it from a cutting from an old gentleman who warned me that it is very proloific grower.  Well it is OK with me, hasn't spread but has just grown bigger and bigger.  I love it and last month it was an absolute picture (  but I didn't photograph it in time) Will keep an eye on it next spring and try to get a close up of the flower. Thanks.
