Ok, I've had with Sambucus 'Black Beauty'. For the third year in a row, this year's new growth has collapsed after one day last week of high winds. It seems it has a fundamental weakness at the point where this years growth emerges from the woodier stems of previous years. I grow it beside a Spirea for the nice colour contrast but now determined to get rid. Unless anyone knows of a solution short of moving house to a less windy spot! What purple foliage plant could I replace it with - Cotinus?
