I was surprised to see neither of these two plants have been the featured "Daylily of the Day". I have both of these and I am wondering if is just me and my soil or do these dormants just not do anything this far south. My sister in law has Stella De Ora In Tennessee, and it does fantastic every year for years.
Neither of these two plants has managed to multiply and both are nearly completely weakened to the point I am about to give up on them. I like that they are rust resistant to some degree, but they just don't perform for me.
Does anyone down as far as zone 8 or higher have any luck with these two plants?

Larry, I have both of these and so far they have performed well for me. I say that and will add this, they have been transplanted about every three years so far, which may have contributed to their survival so far. Stella is a wispy little clump of about 10-15 fans. Happy Returns is potted and has performed ok as well... The local box store here sold a ton of HR, but that doesn't mean anything. It seems that sometimes they sell things that they shouldn't.

@Seedfork @GaNinFl

I have been investigating "dormancy" in daylilies for a number of years. It would be very helpful if I could get as much information as possible about how Stella and Happy Returns behave for you in zone 8b.
Although these plants are registered as "dormants", researchers have determined that Stella (and therefore presumably Happy Returns) does not require cold to grow and flower. However, that does not mean that they necessarily grow well at high temperatures.
Researchers also determined that some daylilies grow well at 75F but do very poorly at 85F and above. I suspect that for some daylily cultivars, their best growing temperature is near to 78F and the further above that, the worse they grow.

Some questions, if I may.
1. Do you grow them in full sun, full shade or part sun/shade?
2. Do the plants keep each individual leaf for about the same time as other cultivars that grow well in your garden or do their leaves yellow and dry, individually, somewhat more quickly throughout the growing season? In other words, do their fans look full or do they look more straggly?
3. When (if) they flower, how many buds do they have?
4. Do some of the buds on their scapes never manage to flower (they develop partly and then they dry and drop off, for example)?
5. Do some of their scapes start to develop and then they die and dry up?
6. Do the plants disappear completely underground at any time of the year?
7. Do the plants stop growing (stop producing new leaves) at any time of the year?
8. If they do disappear underground, how long do they stay below ground before they sprout? Or when do they disappear and when do they reappear?
9. Do their leaves grow normally or very slowly after the plants sprout and appear above ground?

I will have to pay more attention, I will print out you list of questions and if my Stella and my Happy Returns bloom or even survive till next year I will try to answer them.

Maurice,
Answers below are primarily for Stella de Oro, due to not many stats being kept for Happy Returns.
Info to note: All of my CVs were relocated in the fall of 2015 with some making it into their designated beds in the Spring of 2016, and some remaining potted. SDO is planted in sandy soil with mushroom compost, garden soil and alfalfa pellet amendments. HR is potted in a 3 gl. nursery container. Milorganite and Sta-Green 10-10-10 fertilizer being applied up to three times per year, and receiving water every other day via a well water feed irrigation system.

1. Do you grow them in full sun, full shade or part sun/shade?
A. Yes, they receive at least 6+ hrs.

2. Do the plants keep each individual leaf for about the same time as other cultivars that grow well in your garden or do their leaves yellow and dry, individually, somewhat more quickly throughout the growing season? In other words, do their fans look full or do they look more straggly?
A. I would say both produce full fans. The fans stay near full until they begin to go dormant, but do experience some die off of older leaves thru the growing season. Currently, Stella de Ora is completely dormant with all the foliage dying back. I'll have to look at HR to report status.

3. When (if) they flower, how many buds do they have, and 4. Do some of the buds on their scapes never manage to flower (they develop partly and then they dry and drop off, for example)?
A. I am guilty of not tracking stats on a lot of the CVs I have, but if memory serves correct, I would say each scape has around 6-8 buds. I did experience some bud drop but perhaps, a very rough estimate of 70-80% went to maturity.

5. Do some of their scapes start to develop and then they die and dry up?
A. Did not notice any scape loss

6. Do the plants disappear completely underground at any time of the year?
A. Yes, I will attempt to get pictures and update this forum tomorrow.

7. Do the plants stop growing (stop producing new leaves) at any time of the year?
A. This year we experienced an unusually dry Sept-Nov. Even with regular watering I saw a lot of late season inactivity with all of my CV's. We've also experienced unusual temps as of late with the weekend mercury marking in the mid-70s. That and recent rains have many of my CVs sprouting new growth, but believe it is limited to those semi evergreen and some of the Evergreens. Today we are experiencing more seasonal temps for only the second time since fall. Which, may stunt or slow their progress.

8. If they do disappear underground, how long do they stay below ground before they sprout? Or when do they disappear and when do they reappear?
A. I will attempt to keep note of this and try to update.

9. Do their leaves grow normally or very slowly after the plants sprout and appear above ground?
A. Normal to regular growth.
