H. citrina - discovered by Baroni in 1898.
My family and I own a cottage in western PA, or which about 1 acre of the property used to belong to a daylily farm in the 1960's. There are many NOID's growing 'wild' there now. Every year I bring a couple of these "old fashioned" dips back home with me. It generally takes them a couple of years to settle in.
Currently, I don't want to "mix" any of the new cultivars with these oldies, and to help revive them, I have purposely purchased some older ones to take up there. H. citrina was one of those. But, I ended up planting it at the house because it arrived after my vacation, so I just popped it in the ground, planning on moving it the next spring.
Well, I fell in love with that oldie. Simple yellow flowers, nocturnal and fragrant, it will always have a spot at my house. I just love it. I also have a few others, but I am at work right now, so I can't post any photos either. I will try to get a better list tonight.
