How long do Lupins live?
Hi everyone. It mentioned in the latest Gardeners' World blog that Lupins are only short-lived. Just wondered roughly how many years they live for, and how to identify if one is on the way out. I have quite a few in my garden and I've noticed that one of them has only very small flowers this year compared to the others - perhaps only 2 to 3 inches tall. Does that mean it is on the way out?
