I would like to add one rose to my herb garden, and don't generally have real good luck with roses. I plan to use the petals in lotions and rinses. So, looking for a very fragrant rose with lots of flowers, preferably long blooming rather than all at once. Any suggestions? I live in the Pacific NW with cold damp winters, pleasant summers. The intended spot will have full sun, good air circulation, and rich soil. Thanks in advance. Deb
