    I have taken an interest in the wildflowers which grow on my sisters property in shohola, PA. This flower growers there, they are a paler blue but exactly the same in shape. I noticed PA was not marked for this flower.

    I also would
    Ike to know if there is a way to identify some photos I took? I cannot find these 2 flowers anywhere on the Internet.
    Thank you for your time. I can also supply you with a photo of this one if you like

      Patricia – A key is the center of the flower. If it is reddish, as on this page, then it’s probably Houstonia pusilla, despite it not being shown for Pennsylvania in the USDA records. It is known in Maryland, so it wouldn’t be much of a surprise to have spread into Pennsylvania, especially southern Pennsylvania, with the warmer weather we’ve had over the past decade or so. If the flower has a yellow center, then it is probably either Houstonia caerulea or Houstonia serpyllifolia. Both of those species may also be a paler coloration, although any of them will have variation in color.
