Deadheading Lupins

When deadheading Lupins, where does the second fgrowth of flowers come from - the same stem or a new stem?
I have read that by cutting the faded Lupins back to ground level, a new growth of flowers will emerge.

Is this a whole new stem emanating from the crown, or from the same stem? I had alwasy believed that to prompt re-growth it was neccesscary to cut to a bud, but if you are cutting below the flower spike there are no buds.

Actually I have not heard of anyone deadheading lupines but definitly cutting them back to the ground will not get then to rebloom except maybe in CA. What I've read is that you deadhead the flower stalk and just maybe it will rebloom but not as vivacious as the original.

So the flower spikes grow from the same old stem?

That's my understanding.

Deadheading Lupines

I've read they reseed themselves. If you cut them off they might rebloom in Sept.

Happy planting.. :)
:wink: Happy gardening!
