I have a plant I bought as 'Miss Jessie' five or six years ago:
- It does have fragrance,
- blooms prolifically
- and increases well.

In my garden, it is in shade part of the day.

Never heard of 'Cleo', but my pic looks very similar?

My son grows this hauntingly beautiful plant. I just wanted to make the observation that 'Cleo' is very very similar to another Historic Daylily called 'Miss Jessie' 1956 I do not grow Miss Jessie, nor does my son, but we have been told that you can distinguish the two by the fact that "Cleo' is 8 inches taller as Miss Jessie will not get taller than 42''inches and is supposed to bloom alittle earlier. I also find it strange that 'Cleo's' original registration lists it as a orange red polychrome with an eyezone and not a mauve purple pink and pale yellow with eyezone, but yet we know of Cleo growing in historic gardens true to name apparently since around almost the time it was released/came out and its mauve and yellow color is said to be correct by these reputable old collections. I would also recommend getting Cleo from Robin Calderon as my son's were definitely 48'' tall first year we had them! Sandra.

I love old daylilies, hoping to get this one added to my garden this year 2012:O)

I won 20 fans of Cleo in an Auction form Earlybird Gardens in Kansas. Robin Calderon who own's Earlybird Gardens, got these years ago from Mr Reinke, who bought one fan of these from five different daylily vendors and kept the healthiest fan with the best historic 1938 Hayward characteristics, tallest scapes and such health, that they even have slight fragrance in the evenings. This is 'thee' Original Cleo, so i would suggest going to Earlybird if you you want some fans of this Classic, Robin has them listed currently at 5 dollars a piece!!! and these are the originals. Cleo is awesome, she has 48 inch scapes and her pale yellow and lavender pink just glows on her like an extraterrestrial being in the late July Sun. What a Truely Historic Beauty..peace..mike

One of my acquaintances has what she calls Cleo daylilies in her garden, but they are fragrant. They look just like the ones pictured for Hemerocallis, but it clearly states these are not fragrant.

Does anyone know of a variety that looks like Cleo but has abundant fragrance?

I love the bloom on this one but the scapes are so tall they fall over. It really needs to be in bed with larger plants to help hold up the scapes. Hayward-1938
