Sweet alyssum. Nicely fragrant. Has been re-seeding itself in containers and on the ground.
Chilian jasmine. Nicely fragrant. It hasn't been getting the TLC that it needs, but manages to survive.
A white-flowered sedum. Very hardy, extremely easy to grow, prevents weeds, stays compact, can be spread over a large area wtih no-effort cuttings. In the winter, I just cut off pieecs and stick them into the ground. That's all.
Pascali. One of the all-time winners. It still hasn't settled in here. I'm not giving it a lot of care, either. So far not much fragrance.
I think that this rose is called
Jennifer. It's a bit like the variety 'popcorn'. Very hardy. The catalog claimed so fragrant you can smell it at a distance. Not.
Trumpet lily. Not perfectly white, but the only white lily that I have blooming right now. I can't tell if it's fragrant.
