question:

do patterns, like the broken eyezone on New Design, depend on the day and/or night temps?


I think warmer = more patterned?


Thank You!

Hi Mayo!

There's is a whole lot I don't know about patterns, of any kind. I do know that the "cobraskinned" ones I have, like JERRY HYATT or UPGRADE or PURPLE CHEETAH seem to actually show off more in cooler temps.

I have far fewer broken patterns and they are quite variable, but I am not sure why. I think some do better after they clump up. Many for me have been tender and struggle in my zone 5 so I only see the first year, which is spectacular, but then they disappear completely. Luddy's and Townsend's have done well here for the most part.....looking amazing year after year, regardless of the temp. I even had WHALE TAILS for many years which was supposed to be tender, and it was very impressive bloom after bloom.

Still others will have broken patterns on a percentage of their blooms, not every one...even in a large established clump. Didn't seem weather related, but more to do with the consistency of the trait of a particular plant.

Just my own observations....not scientific in the least....lol.

Mayo,
It depends on the particular daylily. We have collected and crossed patterns for a few years. The daylily New Design is one that I would think may display more broken pattern in warmer weather or less consistent than some. I am only guessing since I don't grow it but have others from the hybridizer. It is also dormant and from lines of more northern patterns. Some of the well known patterned daylilies will display the pattern at 40 degrees or 100 degrees.
Steve is correct that some are not that hardy. I have lost some in the first winter in my zone 7A garden.
I think I understand some of this because of my interest in crossing patterns and having several thousand seedlings from them. It has everything to do with the genetic lines and the evergreens and more tender patterned cultivars have the patterns bred into them where you get consistent blooms and greater ability to pass on pattern characteristics.

The pigments that are involved in the broken flower colours (flavonoids - anthocyanins, etc) are strongly affected by temperature and light. I suspect that both low temperature and low light (cloudy, overcast days that tend to be associated with low temperatures during warm seasons) cause some of the variability in the broken colour patterns.

You could try a couple of simple experiments.
Use closed buds from the same patterned cultivar picked the day before they are about to open. Place them in a glass with a little water to cover the end of the stem.
Place one bud in a refrigerator (cold and dark) and examine its patterns after it opens the next day.
Place another bud only in the dark (warm and dark) and examine its patterns after it opens the next day.
A third bud could be placed directly under (and close to) a light left on continuously from the day before the bud is about to open until after it opens (warm and light) and its patterns could be compared to those of the other two buds.

You might want to take a sequence of photographs of the flowers as I expect that the patterns will start to slowly change after they are taken out of the dark and the flowers warm up.

thank you all for your info!

Maurice, I don't have any patterned DL's yet.
I'm trying to decide whether it is worth my money to buy some... Big Grin
Over here 3 consecutive days of 85F is considered a heatwave, so that tells you enough about our Summers Hilarious!

If patterns are only showing when the Summers are hot, I am better of buying non-patterned DL's

Mayo,
I think you would find several of the southern patterns would bloom consistently. The pattern in many of these has been bred for more generations. Carpenter pattern lines bloom patterns in my garden no matter the weather. Several southern hybridizers use these genetics. I do the same. You could get seeds and start that way.
