Karen,
Smell the flowers in the evening/night time ... some Hoya blooms are very fragrant! Although some say the carnosa bloom is fragrant, I have a couple of Hoya carnosa plants but my nose has never detected fragrance. I should get my husband to smell them though because I've had night blooming orchid cactus in the past that are very fragrant and I only detect a slight scent on those while others say they are extremely fragrant!
