Do you have access to the original phone/camera that this picture was on? It looks like you took a picture with a phone and then took another picture of that phone showing the picture on its tiny LCD. If you do have the original handy, either upload that picture or ask a friend to use their computer to upload the picture there if you are lacking in a computer of your own.
Where in Hardiness Zones 5/6 are you? There is a massive difference in the plants living in the foothills of the Washington Cascade Mountains and the middle of Kansas which are both in HZ 5/6. That would help narrow things down. :p
You got it, I took a picture of the cellphone screen, which took the original shot.
Unfortunately, I don't think I can access the original because the person's cellphone doesn't work other than taking photos.
It may be possible to transfer them to another device sometime. But that likely won't happen so don't hold your breathe.
I realize the image is bad, I'm not going to loose any sleep if I don't get an answer.
If anyone has a rough idea what it might be, maybe I can search the plant name for a better image?
