Justin, thanks for starting this thread and compiling all the information on them. These are one of my favorite wildflowers which I call Texas bluebells. I have some growing in my garden and they have spread to other parts of my garden
I've collected some of the seed pods so I'll have some more to sow and to share.
Lovely photo of you, Josephine, among the bluebells; I've not seen a field like that!
