Can anyone suggest a "substantial" flowering perennial (or annual) for the
back of a border in a corner. I had verbena bonariensis last year, but it
was too see-through and didn't have enough presence. I want something
heavier and bulkier, with more oomph.

Acanthus mollis, Telekia speciosa or maybe Cardoon

The first has oomph, all right. You plant it there and, before you
get time to blink, it has sprouted up 6' away - under the lawn as
well as in the flower beds. It took me a decade to eradicate.
