Sorry folks for the name, another of my cheapy buys. No idea if it has a garden name.
I fell in love with the lovely grey silver foliage. It belongs to the aster family, very similar to helichrysums. It needs poor soil and a hot, dry, sunny position so it is going at the base of my 8ft wind break fence which runs along the top of a south facing bank. The flowers are tiny, white so not very noticeable amongst the silver foliage. I thas a bushy growth and the whippy, branches have tiny aromatic leaves which look almost like thorns.
Another yummy plant.
