H. Citrina has been around for over 100 years. It is a pretty trumpet shaped flower which is fragrant.
Also Toltec Sundial.
I also have an unregistered spider seedling of Fred's that is nocturnal.
Non daylilies - Stemless Evening Primrose - but be careful, it is considered invasive in some locals. It isn't here because of my zone. Also Moonflowers, which are related to Morning Glorys.
