Lowe's carries mostly roses from Certified. Here's a link to their catalog. I don't recognize that rose, but maybe you'll see something that you recall from the label in this catalog.

Thanks!! I had no idea they had that catalog! I don't really see anything that matches either. We really thought they were white but the blooms ended up with that little bit of pink. I think Pristine is the closest but i'm still not sure. I'll have to analyze a bloom that isn't so open.

Flower looks too undeveloped to be a contemporary cultivar, more like a seedling that would never make the cut under today's standards. Maybe somebody was using seedlings as root stocks and that's how you ended up with it, the rose grafted onto it having died since it got planted there.

Or maybe it produces fuller flowers from other buds.

The color of the blooms reminds me of Sheer Bliss, although I can't say if your rose is Sheer Bliss....

Sheer Bliss does have lovely fragrance, and beautiful blooms.

I think that Krista's guess is a very good one.
