Orchid with the LONGEST-LASTING scent

[Gage]

In my experience, some of the Brassavola nodosa hybrids tend to be fragrant day and night. ie Bc. Adrienne Arsht, which smells strong and peppery, and is fragrant all hours of the day and night. I will note that the fragrance does change some between day and night, I would assume from the Cattleya parent being fragrant in the morning and the Brassavola parent being fragrant at night.
