I don't think any of large flowering phal hybrids are scented.
I have a large flowering hybrid which actually doesn't smell very nice at all until the flowers have been open for a couple of weeks. Then the smell changes and becomes very sweet for a couple of days only. Very, very, strange.
First time it happened I thought I'd imagined it, but this year I made sure to make hubby take a whiff so I knew I wasn't going mad.
