Can anyone identify this plant, and if so, can you share some information about it?
I'm particularly interested in propagating it, (If my neighbor will allow it:)

looks like a delphinium ....no idea which one

The leaves looks like delphinium, except that the flowers are only on the top of the plant.
I quickly looked at a few pictures (google) and didn't see anything like this.

It's a Monkshood (Aconitum sp.). This particular one might be tuberous, which would make it easy to propagate. If it is, usually each stem will have its own vertical tuber. You could separate them now or in the early spring. if you do it now, be sure to cut the flowers off. Cut the stem back by half.

Thank You, it is indeed Monkshood. I live in a pretty hot and humid area. I have no idea how my neighbor had success with this plant. I was hoping to propagate it without having to ask my neighbor to dig up a tuber.
I've read conflicting information on it though. I have seen that it grows from seed, and also read that it does not come true from seed.
Do you know if there is a way to propagate it from a stem cutting?
Thank You!

Don't know about stem cuttings, but if it is an option then it is too late in the season. I would guess that late spring or early summer is what they would recommend.

You can grow it from seed, but if it is a hybrid, that is when it may not come true. If your neighbor knows the variety name of it, you could find out. If it is an Aconitum species, it will come true from seed. Aconitum seed is recalcitrant, meaning you can't let it dry out before you plant it, like you do with most seeds. Ripe seed should be planted within 2-3 weeks (the earlier the better), although it won't sprout until the following spring.

Thank you so much! I appreciate you sharing your knowledge with me.
Cheers!
