As I posted recently somewhere here: my most intensely fragrant orchid is Pot. Hawaiian Charisma 'Hilo Beauty' I've had it for years. I have to give away the divisions I pot up cause of limited room.
It blooms all year, vivid and lovely, good form, and the scent is so intense it infuses my whole apartment. Nobody can believe it. Even I can't sometimes.
I will put up a pic of last bloom; it's now in sheath on three bulbs. You want intense fragrance? This is one of the hybrids you might consider, also a fab grower.
