Here's another photo showing the leaves. Thanks!

Yes, I believe it is Catchfly. I checked out this forum on my lunch break but did not have time to respond. I checked out each suggestion, but I could not find anything that came close to the color of my flowers until I searched Catchfly. Thank you all very much for trying to ID this plant for me. I have no idea where it came from, but I hope it likes it here. I will try and save seeds, and then put them in a sunnier location. By the way, I really prefer the name 'silene'. Could they not have found a more pleasant sounding name than 'Viscaria vulgaris'? I so much appreciate the help, and greatly enjoy the photos on the GardenWeb forums. Jane

Oldroser, I am excited, I think it may be a shadblow, I've googled them and they look so much like my tree...except mine is pink. And a lot taller than they usually get apparantly (the wild ones I see tend to be under 20') although one site says they can reach 40' but that size is very rare. I also have never noticed fruits on it but that may be because the birds notice them first! I have a friend who is a botanist take look at the tree in bloom and she did not know what it was - I think I'll run the possibility of a genetic variation of the shadblow by her. Whatever it is, it sure is beautiful. Our wild apples are not blooming yet either but will be soon. I love spring!

Maybe another species? multiflorum? For some reason I cannot direct link to Calscape so you will have to search the species. https://www.anniesannuals.com/plants/view/?id=3362 http://calscape.org/Dichelostemma-multiflorum-()
