Thanks Verdun. I grow the Goldsturm in another part of the border and it's brilliant - don't need to do anything to it. Thought I'd try this Rudbeckia Laciniata Goldquelle as I wanted another yellow perennial. I tried a Helenium, which just fell over, as did a Helianthus. Must say, it's quite difficult finding a chosen colour with the right height and habit, without the need for staking.
