Morning Glories 2007 # 24

Emma, You can segregate vines on the smaller nils especially if they bloom quickly before they gain very much size but the purpureas are indeed a different story. With this one I`ll have to tag blooms and try to follow pieces of the vine.

I`m going out for pictures and will be back later! Karen

This is from this morning. I cut a piece and dipped it in rooting hormone to see if I could root it. I marked pieces of vines for seeds later.

Here are some of the colors I find on this mass of vines. I marked each color of vine with tags. Karen

The extreme dilute versions of Joyce Cobb look alot like "Milky Way." I have some of these seeds but havent grown them, called "Parks Pink Swirl" off ebay.

Ron says the Pink Swirl came out of flaked purpureas and not the Joyce Cobb. The ebay seller is incorrectly identifying them as dilute Joyce Cobb.

Here is a comparison photo of Milky Way and what I think according to what I have been told is dilute Joyce Cobb. The Milky Way has sharp "eyes" against a white background and the Dilute Joyce Cobb has fuzziness to the "eyes" and subtle shadings.

Good comparison photos. This is the Pink Swirl.

Okay,I'm going to indefinitely RETRACT my assessment of the Pink Swirl as resulting from the flaked strain...

The reason is that although I have seen a bloom pattern that looks remarkably similar to this 'swirly' thing come out of the flaked strains (as reported in some journal articles devoted to studying the flaked variations) >I can't be absolutely sure (at this point) that this dilute pattern is also not resulting from Joyce Cobb dilutions...even though the gene combinations responsible should be different

I may have to go back and fix up my previous posts if this pattern turns out to be resulting from the Joyce Cobb...

My interpreatation was based on the following

The Milky Way has a different type of spotting in that the color along the primary fold is 'decrescendo' as it proceeds outward towards the edge of the limb as seen in the photo here

the spotting 'star' gets thinner/pointier as it proceeds outward...

The dilute Joyce Cobbs that I am used to seeing come out of the Joyce Cobb have previously all had a star that splays outward > becomes wider(shaped sort of like a candle flame) as it proceeds outward and have all had an all white(!) throat as seen here

The unusual variant that has been reported as coming out of the flaked strains looked like this with the pink brushed striations coming out of the throat

but now it does appear that this same pattern with the pink 'brushing' could also be resulting from the Joyce Cobb dilutions...

So,until I have oppurtunity to look further into this color pattern >I am retracting my previous assessment that the variation with the pinkish in the throat only comes out of the flaked strains...

Sandy - can you tag some yarn onto some of the aqua blooms...

Revclaus - I wanted to mention in relation to your question about the Rebecca to be mindful of the time of day that you are seeing the colors and definitely watch the direction that the color pigment seems to be progressing towards >that is to say is the color progressing toward a >more dilute(?) or more solid > like it is filling in > to the point where it will look like a regular purp...

The Joyce Cobbs and the Rebeccas can make a pattern directional 'turn' and go in either direction...

Karen-blue - The highly bred nils are more 'persnickety' about fertilization in the summer heat because they are no longer wild plants that can survive environmental extremes...they are accustomed to being taken care of like 'pets'...the extreme temperatures causes the pollen to fail to fluff up,the other important structures to malform and the repoductive parts to prematurely senesce...this is extremely common and can be seen as the stigma and anthers look to have an off color 'brown-ish' bruised appearence...sometimes before(!) the flower even opens...

Somebody(?) asked the following
"...that shorter days bring on flowering - does anyone know if it matters whether the shorter days are decreasing in the fall or increasing in the spring?"

If I understand your question correctly it does matter...the MG's flower better in response to a gradual shortening of the days = a longer dark period than to a gradual lengthening of the days even if the approximate periods are the same...

So,they should flower better in the Autumn than in the Springtime which is most often the case = better flowering as the season progresses towards the Fall...

Hope that helps...

TTY,...

Ron

P.S. - Apologize for any temporary confusion regarding the spotted dilutes...I do try my best to be sure of what I'm saying before I say it >but I'm human and a 'rare' mistake is therefore unavoidable...smirking like a devil anyway...

I can try Ron! If I see any more blooms that color I will definitely tag them....

Karen . . .

Your color combos are remarkable in your Joyce Cobb - Love them.

Beth . . .
I REALLY like this bloom
http://davesgarden.com/community/forums/fp.php?pid=3968198
and would love to have some of your seeds if I don't spot them on eBay.

Ron . . .
THANKS SO MUCH FOR ALL OF THAT INFORMATION

Emma

Yes, Ron. What would we novices do if it weren't for your help? Thanks very much. You too Emma.

I'll make a note to send you some, Emma.

Thanks Beth, I appreciate that.
Emma

Well, I just spent some time reading this whole thread and thought I would throw in a photo of my "dilute" Joyce Cobb.

I have a bizillion seeds that I collected from Joyce Cobb if anyone wants any...although someone posted elsewhere that they thought it could revert to the common purpurea?
