I'm actually thankful that some roses have no fragrance. If all of my roses had a strong scent, I wouldn't be able to go outside.
My favorite rose for fragrance is First Kiss. It's not a strong fragrance, but it somehow wafts out from the bush, so that I can smell it as I walk by.
I'm also fond of roses that smell like raspberries. The best are Zephirine Drouhin and Madam Isaac Pereire.
