Plant ID: Flowers_Purple trumpets

These flowers were in bloom around late September - October.
Hardiness zone: 5/6

Sorry for the bad pic.

Anyone know what it is?

These look a lot like a petunia variety. There are bush type and annual type petunias I think, but I'd check for what the native petunias to your area are if you can. It could be something completely different too.

Second look, no I don't think they're petunias. I didn't notice the bottom two long petals.

I would guess some kind of Lobelia.....

What size are the flowers/plant we are looking at?

Mostly based on assumed size, bloom time, and color I'm guessing monkshood? I don't think it is but I can't really see details on the flower to be sure. But if it is be careful as touching it enough is toxic.

The picture is a bit fuzzy and I can't make out the leaves, it could be a Campenula variety?

Possibly some kind of larkspur. How tall is it and what do the leaves look like?

Yes, that really is a bad pic. Not petunia, and probably not larkspur either. Lobelia and monkshood are possibilities, also penstemon and salvia.

Unfortunately I don't know anything else about the plant (size, leaves, etc.)
I didn't get to see the plant in person. I'm merely posting the pics that someone else took.
When I get a chance to talk to the photographer I'll try to gather more info.
