My mixed border is lacking pizzaz at the moment. I'm anticipating lots of
colour from late summer into autumn (sedum, rudbeckia, aster, anenome,
echinacea, verbena bonariensis), but it's become glaringly obvious that I've
not planted anything for this time of year.

So, what colourful perennials are in full bloom in your gardens right now
(particularly in North West England)?

Many Thanks
