|I've really enjoyed reading each of these letter threads, to everyone for the thoughtful and creative additions!
One "Z" this morning to get the last of our alphabet threads started.
When I first designed the display garden each area was a separate themed bed. There was a Candy bed for the "candy" series of daylilies and a Double or Nothing bed for double forms. The Earth, Wind and Fire bed had Mystical Rainbow, Earth Music, Desert Flame and others. The After Dark bed was for the naughty daylilies, Girls Night Out, Women Seeking Men, Pineapple Daiquiri, Long Legged Lap Dancer... Over the years all the theme beds have been rearranged, daylilies moved out to make room for new ones and the themes are gone. Some day, when I get serious about down sizing the display garden, I plan to do a few theme beds again. One theme I would like to do is a "Welcome to the Zoo" bed which might include...
Lions, Tigers and Bears.

|"Zone" as in USDA Hardiness zones. We should all know what zone we are in because it is important for determining the hardiness of many plants. However according to this source below the USDA zones do not really apply to daylilies.
Go down to FAQ # 4
I googled this assessment of USDA zones and daylilies and this was the only site I found stating this. Even university sites referenced USDA zones when discussing daylily hardiness. I could only find references to temperatures when determining USDA zones, and no particular plant types. Does anyone have any other sources for USDA zones applying only to woody type plants?

"A BRIEF HISTORY OF HARDINESS ZONES AND ZONE MAPS. A relatively
simple method used to visualize geographic patterns of the biological severity of low-temperature events is to map a climatological variable that closely
correlates with patterns of plant survival. Rehder (1927) developed the ﬁrst such map for the United States, with a mapped zonation system that related winter minimum temperatures to the survival of speciﬁc woody plants. He roughly divided the temperate portion of the conterminous United States and southern Canada into eight zones based on the mean temperature of the coldest month, each zone spanning 2.8 degrees C (5 degrees F)."
The above quoted from Horticultural Applications of a Newly Revised
USDA Plant Hardiness Zone Map, 2012, Widrlechner et al. You can get the PDF by searching on Google, a direct link would be too long to include here.
Other factors do come into play with woody plant hardiness as well as herbaceous plant hardiness but the USDA zone system is based on air temperature minimums. The survival part of a daylily is the crown which is below ground, and not exposed to air temperature. If there's mulch or snow cover, then there is even more protection from air temperature. Where I am there is no freeze-thaw during winter, the ground stays frozen right through, so some daylilies can be hardy here but not so much in milder zones if they keep trying to grow in warmer spells.
Instead of using a zone map, one can instead use indicator plants that have been established for each zone. These are all woody plants. I can't get the USDA list to work right now, but here is the Cornell page for New York:

|Lovely themes, Char!
I have often fantasized about the themed beds that I would have, if I ever had the right property to do such a thing. I would keep the doubles in one bed (at one time, I had a bed of mostly doubles here). "Double or Nothing" is a wonderful name for such a bed.
Interesting discussion about zones. I recall, many years ago, having arguments with a certain mail-order nursery wrt certain plants that I wanted. They were convinced that I was doomed to fail with these plants, since I live in Zone 9, and the plants were only rated to Zone 8. (Apart from not wanting a disappointed customer, I suspect they may also not have wanted to have issues with refunds or replacing plants.) I had to argue them into sending me the plants I wanted (I forget what they were... they may have included some daffodils); I may have (I can't remember) had to agree not to blame them if the plants failed - which, of course, they didn't. (At that time, that (East Coast) nursery had not yet come to the realization that Zone 9 in the arid West is a different thing entirely from Zone 9 in the humid South.)
I'm afraid that the only offering I have for today is zombie.
Let me explain.
Last year I had several spring volunteer seedlings, all or most (I can't remember which) of them in certain form factor 4-5" black pots (recycled from online nursery orders). From spring through fall I watched one or another of these seedlings die (drought, rot, what have you), and kept notes as to which ones were still alive.
The pots (both live and "dead") lay out on the ground in my side yard until January (other things to do, no place yet to put the live ones once potted up), when I was able to get around to them. I had all of the "live" ones in one place so I took care of those, then went back later (by then, in was mid-February) and started cleaning up several pots of "dead" things (not just those seedlings).
One of those special pots had been tipped on its side; there were two labels on the ground nearby. One label indicated one of the spring volunteers (which was on my "dead" list), the other indicated a cross between a dormant and a Sev-Dor seedling of mine.
When I picked up the pot to go empty out the dirt, there, in the bottom (half the dirt was missing) was an emerging green shoot - which was not a weed, but clearly a daylily!
Maybe this was something that went into dormancy REALLY early , and stayed that way until mid-February, or it was a zombie. *need fear icon here*
I put the seedling with the rest of the spring volunteers... you may be sure that I am keeping a close watch on it, though!
