This is one of my all time favorites, probably because...1) it hasn't died on me, 2)it gets bigger and better each blooming season and 3)again..it hasn't died on me yet
(I lost a lot this past summer.)
Mine was a Better-Gro bagged plant, in a 4 inch pot that I bought a few years ago. I had 10 spikes on it this past month and just upped the pot for the 3rd time to 10 inches.
I've noticed that the blooms put out their fragrance well into the night, usually around 9:00 is when they begin smelling their prettiest.
Hope you're enjoying yours. It's lovely!
Here's mine from this past blooming (before I repotted it).
