 o
Lupinus perennis or Lupinus polyphyllus?

I've had some lupines on my property for about 15 years, and I think I've narrowed down the species to either Lupinus perennis or Lupinus polyphyllus. The trouble is, I'm not really sure what to look for to tell them apart! I've heard that Lupinus perennis is a species native to Maine, where I live, but that Lupinus polyphyllus is invasive. I'm not sure if anyone could provide an ID with the picture I have, but knowing the key differences between the two would be really helpful. Also, if this lupine does prove to be an invasive species, what should I do with it?

Additionally- the tallest point of the plant is about 5ft. The largest leaves are slightly bigger than my hand.

the link below states a difference as:
Lupinus perennis "Leaves are divided into 7 to 11 leaflets"
and
"A similar species in Minnesota is Large-leaved Lupine (Lupinus polyphyllus), a non-native introduced by gardeners which has become invasive especially along the north shore of Lake Superior. It is overall a larger plant with taller spikes and 9 to 17 leaflets."

eta:
it is my understanding that there can easily be cross-breeding as well.

Here is a link that might be useful: minn. wildflowers - wild lupine

Lupinus perennis. I have several on my property and the photo of your plant is a carbon copy of my plants.

Awesome! That's great to know- thank you both so much for your help! I think these might be Lupinus Polyphyllus, because the stalks were well over 2 feet in height.
