There's not much sense of scale here, but I can tell you that the flowering starts at about my head height.
If you grow the green-leaved variety, then you might prefer to allow it to flower, as their flowering is much more of a golden affair... but for me, I would only ever give garden space to the purple-leaved ones, on the basis that there is enough greenery in the garden already!
I wrote a piece about annual pruning of Cotinus for GreenPlantSwap last week - so if you'd like to read a little bit about how to do it, head on over there!
