I have succesfully grown lupins for several years but this year the plants appear wilted and although the flowers are a good 1 foot long they have bent in half. It now looks as though the plants are dying - any suggestions please?
Are they in pots? If so, look for damaged roots, perhaps by vine weevil?
I have a lupin which has just done the same thing. A week ago I was admiring the 13+ flower spikes on it, and suddenly they all went like an upside-down U. I put it down to the heavy rain and winds we have been having - although my husband pointed out that our neighbours lupins were not affected. The plant is just coming into its third flowering season, and is planted into good soil. I would love to know what is causing it. Any ideas?

stupid edit not working! Tries again...
I've also got this problem. I left them out overnight after buying them planning on planting them in the ground the next day. There was strong wind that night and the next morning the lupins were drooping.
My lupins have been in the ground for about 3 years now. Last week some of the flower heads all started drooping bending back on themselves, however after a few days amazingly they have righted themselves.
If the plants are newly bought, check the root systems before planting out. Nurseries force plants along to keep a schedule of sales and we've had atrocious weather to boot. Your plants may be growing beyond what they can sustain.
Last year I bought a rose from B&Q that had absolutely no roots and had to leave it in its pot for the rest of the season.
is there anything we can do once they've drooped?
You can try tying them to a cane. keep them watered and in a sheltered position and there's a chance that they will recover.
