If he doesn't want them, you can send them to me.

They look like Aconitum, common name Monkshood, judging by the foliage, though I could be wrong - beautiful flowers, but deadly if eaten, I love 'em.. its said they are toxic to touch, but I never had a problem with mine like that and I obviously handled the plant. Info here on that aspect

I agree it is monks hood. Aconitum. There are several species that flower at different times. Also white and pink ones are available. This could be napellus or carmichaeli, i can never remember which is which.

If he loves these and doesn't love the idea of them being highly toxic tell him to look at the various kinds of campanulas (there are tall ones and short ones)

Thanks a million for the info. Obviously why i never found them in the delphinium selections. I thought these would be good because of how high they grow and because they don't tend to flop over in wind. Thanks again.
