Yes. I would think so. My lupins have come back into flower and I live in northeast England

You could collect some seed heads from the ones that have finished flowering,and dry them off,if you want to sow some for next year,or sometimes,they will seed themselves in the ground,if you leave them..I still have quite a few in flower too,with new ones appearing..

My pelargoniums on the balcony are all flowering away merrily...
