Funny thing. A couple of years back in a friend's garden, I hacked back viciously an overgrown Darwinii actually hoping it would die. I wanted to plant a camelia there instead. However, it thrived.
yes,,it will dig out Harrers. The roots do spread a little in my experience. How about a vigorous dahlia in its place? The Bishop with its dark foliage will provide a long season of interest ...??
