Katrina - I only just got this a year ago, as it was nearly finished blooming, so I don't know how long the blooms will last. The first that opened still look good after 2 weeks or so ...
Subrosa - When I am just outside in the vicinity of the plant, I catch a pleasant scent, but when I put my nose right up to it, it doesn't seem as nice. I also have a kingianum blooming near-by, which I have the same opinion of the scent.
