This is a seedling from "Muscosa Rubra", OP.
It is for sure a mossy Rugosa.
Stine is the rose with the most fragrant leaves I ever seen or smelled ;-). I asked a lot of people what they think that fragrance will be. Some say marcipan or almond, some fruits like oranges, some say pinewood.
Me myself, I recognized that theres a lot of rubiginosa, perhaps the fruity part.
And in fact, checking my notes, I found that when I picked the hips, Muscosa Rubra stood next to Rosa rubiginosa...
