What a great question Verdun.
I love crocosmia Lucifer and last year I put penstemon barbatus in the same border and they worked really well together for me, giving a lovely hot red feel.
The penstemon are still lovely and green now and I have taken cuttings, and I think both are perennial (these are the things I still need to learn). Although I have read conflicting things that say the penstemon is only half hardy I hope it comes back as nicely this year.
Can't wait to see what everyone else says
