planting Rose seeds

Two years ago, I saw an amazing hedge in Germany, edging a parking lot. On a closer look, it turned out to be a rose hedge with giant round red hips. I think it was a rugosa, not really sure.
I picked a hip, and took it home. I broke the hip open, and planted the dozen or so seeds strait into a pot of soil, and forgot about it. Left it outside all winter. Next spring I noticed one of my seedling pots had what I thought were tiny strawberry plants. I transfered them into individual pots, and eventually realised that they were roses! I have a few planted around my garden, my Mom has one of them in her garden now, and there are still 3 in thier pots, see them in the middle of my pic?
So this year I went nuts picking pretty hips from all kinds of roses. And planted seeds from 6 different hips into little pots. (The hips in my pic are googled images, I forgot to take a pic of them, I was in such an excited rush to plant them!!)
I hope they grow!!
