A couple of different shades in the same patch caught my eye, but they look just like the other ones I found.

very pretty

Is it Nigella Damascena please ?

Looks like it. They do come in a range of colors and appear to cross pollinate freely.

It is a fascinating flower and pod!

Yes, Aleema, it is Nigella damascena. I have grown these from seed many times in my garden and I love them. One plant can have several shades on it: light blue, pink, and white. My favorite thing to do with 'Love in a Mist' is to hang them upside down when they develop the seed pods. They dry to a beautiful mauve/beige color and the dry seeds inside the pod make a neat sound. They last for a long time in a basket or wreath.

Cool, do you have any photos please ?

I'm sorry I do not. I had some back in the spring, but we had severe drought, and they didn't make it. I will look through my photo stash and see if I can find a pic from last year.

Plenty of images online. Search <dried nigella seed pods>

Aleema, I searched my photos and I had deleted a plethora of pictures, but Zoe is correct. You can search online and get plenty of photos and information.

There are some images in the database on this site:
Love-in-a-Mist (Nigella damascena)

Be sure to scroll all the way down to the bottom. I love it in fresh bloom, but I also love the dried seedpods. Win-win!

@slowcala: The trouble is that the dried efforts always seem to keep the flower in 3D, rather than pressed into a book (2D).

My photo made it into the database, so I feel I contributed back this time around.

I think it could be a new category : dry flora (not just from bud to decomposition).
