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?

    Earlier this year a lupin that had been in one spot for 6 years was dug up pulled to pieces the pieces replanted in a new spot and this is the result a few weeks back

    since then the wind bashed it about a bit but even so there are now around 30spikes flowering there socks off.

    So they may be short-lived but can easily be rejuvenated by division

    usally after the second year of flowering they tend to go woody and dont flower anymore but there still worth it for early summer display.

    We've had lupins in our garden since we moved in almost 8 years ago, and they were probably there long before that. They are still flowering well and look strong and healthy, except when attacked by slugs, knocked over by gales and (the latest) visited by lupin aphids. I'm not aware that they have a short life.I cut the flowering heads back to a new shoot once they've gone to seed, to prolong the flowering period.

    I think if they set seed, the new plants will always be purple-flowered, but I may be wrong about that.

    Thanks everyone.  Hope mine last a bit longer than a couple of years as I have quite a few!  Sotongeoff, your lupins look amazing - if only I had a big enough garden to have huge groups of lupins like those! image

    It was in March and I did just dig it up, pulled of the outside pieces and replanted those in a different spot-I am amazed it has done as well as it has-so spring or autumn is probably the best time.image
