Lupines Produce Seed Which Will Re-produce More Flowers

Question

Please explain this puzzling sentence-“Lupines produce seed which will re-produce more flowers the following year if not removed from the growing lupine.” I am a long time gardener and have never heard anything like this. I cannot comprehend what you are saying. Thank you

Answer 1

I think what this author means is this: If you leave the flowers, do not deadhead them, and let the seeds dry and fall, they will grow in the spring and produce more flowers. Deadheading the lupines – removing the flowers when they're finished – also removes the seeds, so they will not drop and produce more plants next year.
