I don't think that one does tidy, does it? My son has a huge specimen in
his Jersey garden and one of its charms - for me - is that it flops around
all over the well head like a demented thing!

It looks better as it gets older and I only take out the flowering
shoots every year straight after they have faded. No other pruning. It
has an overall pleasing shape and density to it now.
