What is this plant please

[PattyDuke]

The tall dark blue flower that came with a bunch of flowers. I would love to grow it myself next year. Thank you

I grew Baptisia ‘Purple Smoke’ some years ago, because it has smoky grey foliage and purple flowers. It is a perennial which dies down completely in winter, but I found it spread too much where I had planted it, so eventually dug it out.

Goodness who would have thought this not very clear picture of a plant would generate so much discussion. Thank you I will enjoy my new plants -they look similar maybe not exactly the same - difficult to tell (as still small). However it isn't Delphinium or Larkspur - I have these growing already and thankfully it isn't poisonous.
Many thanks for all the interest - love the gardening threads.

Do you mean your new plant isn’t Delphinium/Larkspur or the one in your original post? Whatever, the one in your OP isn't Baptisia, for the reasons already given

Meredint is correct (as usual!), it's delphinium. Here's a close up of the OP's picture, a baptisia, and a delphinium in bud. You can clearly see the spurs at the back of the flower.

Interesting...I think of Delphiniums as tall blousey plants but then I see Delphinium Belladonna (poisonous) which looks similar.
