SYMPHYOTRICHUM LATERIFLORUM VAR. HORIZONTALE
I fell in love with this on my first trip to Great Dixter, back when Christopher Lloyd was full of energy and it was still an aster. It was a misty morning and the sight of it used as a low hedge, with a backdrop of topiary and late-season perennials was literally life changing. Profusions of white flowers with pink centres make a stunning show but its structure of horizontal, branching stems is possibly its greatest asset. These look good throughout the winter and should be cut down to the ground at the very start of spring. AGM*.
