It has the best fragrance I’ve ever smelled on from a rose..
Wow! That is a special rose.
I tried a very fragrant petunia this year. It is a neon blue/lavender color, called Evening Scentsation, and is sold by Park Seed Company (parkseed.com). I grew them from seed. They are lovely and really do have more sweet scent than other petunias. I already bought more seed for next year. (Photos at parkseed.com)
