Looks like Double Delight, both in bloom and foliage.

BenT I have DD but this looks a bit different. And according to my son, the blooms after they open are almost completely whitish. Whereas with DD, mine at least still always show the vibrant red border. I recall seeing a rose that looks almost identical to DD but it was smaller & the blooms looked similar to the pic. But, maybe it is DD after all, if I can't find the one I'm thinking of for comparison. I'll have to pay a visit and sniff for myself.

DD has petals that start white and the red color is induced by the sun. They get redder with more sun exposure. the blooms open white with the outside petals being red first and by the time the bloom is fully open the whole bloom turns red at the end. In very sunny climates like SoCal they are mostly red. Growing up in Seattle the blooms were mostly white, but it was mostly cloudy there. So If your unknown rose has petals that start out red and get white with age it can’t be DD.
