While on a walk recently, I came across a dazzling plant with clusters
of brilliant yellow and contrasting magenta. With the help of a
friend, I found it to be a Linaria, and I believe the variety is
"Flamenco" (though my friend thought it might be "Crown Jewels").

I dashed off to the nursery where they had one straggily plant left,
with floppy foliage, but with many buds yet to open. I bought it, and
now my question is whether I should cut it way back and hope for
stronger, more upright foliage? Or would that be eliminating the only
chance of flowering for this lovely plant?

Might it come back next year, self-seed, or is this a brief though
lovely addition to my garden?

Thanks.
