To the best of my knowledge, it looks like mine (incense)

Thanks, Omar -- it does look just like yours. Here they are earlier this afternoon:

How long do yours last? I was reading up on the P. caerulea, and apparently the blossoms don't last more than a day or two. The one from the other day hasn't opened back up again (unless, once they close, they close for good.).

Good question, Javi. I think they last two days.

In photos of native P. incarnata that I have seen, flowers were paler. In contrast, Incense always intense.

Many hundreds of Incense in my yard every year. Of course I cannot track all, but I can say that I was very surprised when ONE was open on the second morning.

I wonder if they'll last into Day 2 if the weather's not too hot and/or sunny. So, four, do my flowers look like your Incense? I'd read Incense has a nice fragrance, but I couldn't discern much more than the most slight scent.
