Thanks @Jay 6a Chicago. Thinking about this a bit more, we may be seeing "Vicars Mead" Sylvestris.

I'm thinking now that yours bloomed, they are finished and will die? The Vicar's Mead is very nice too. My gardens are too small for growing huge Angelicas and Lovage. I stick to smaller carrot family plants like Zizia aurea and aptera, Cnidium monnieri, Siam suave, dill and cilantro. I've been trying to start a few others from seed, but so far with no luck. Those would be Heracleum maximum, Thaspium trifoliatum, Polytaenia nuttli, Periderita. The most desired of them all is the small spring wildflower Erigenia bulbosa. I got a A. gigas a few years ago, but it perished before blooming. I grew the Japanese Angelica keiskei. It bloomed in its 2nd year,( last season), but never returned this year, even though it is perennial. Heracleum is the exception I make for growing the large species.

Ooh, those are nice!

Yes I am confident that it how it will go. The question is if there are any of these VM plants which are, say a year behind the ones that are now flowering with the hope that I will get some to flower next season. I cant tell right now as it is a 'mess' of foliage in that location right now.

Wow @Jay 6a Chicago, an impressive list of Apiaceae plants you have mentioned! (Please post pics for any of them that show their stuff to you).

Thanks @porkchop_z5b_MI. I like them also for sure as they are unusual but Its kinda creepy watching this stand of Vicar's Mead as they attract mostly wasps.

Wow, they’re beautiful!!

Rouge your gigas is beautiful. I would love to try it, but I have too many big plants as is. I understand about the wasps, I have had a big bush of purple fennel for years now. Around this time of year it is literally buzzing with wasps of all sizes, from big bald faced hornets to tiny little ones that look like undersized flies, but I have never been stung even once, though the fennel is right along the main path. It is actually interesting to watch all the activity.

I agree completely @gdinieontarioz5 ie I am mesmerized watching such insect activity on these plants. Id love to know why they are so appealing to wasps (and not to "bee" pollinators).

@Jay 6a Chicago I noticed yesterday that the Angelicas have arrived. (The ones with the much darker flower)
