Sunrise Serenade - A study

This morning when i did my walkabout I noticed two types of Sunrise Serenade in bloom. I had camera in hand sooooooooooo



I'll start with the mundane, the leaves.

A round flower

A shredded (please don't call the ASPCMG)

And the icing on the cake ....

You can go here to see 2 in your face shots .. about 2.5 megs.

This is the same as above but with a red shift for detail.

X- Did the solid bloom occur on the same exact plant as the more shredded plant(?)...

The closeup of the reproductive parts would be a great addition to the PF Ipomoea purpurea entry...

TTY,...

The variation of "shredded-ness" on Sunrise Serenade blooms brings up a question in my mind. Why is Sunrise Serenade so varied and Gypsy Bride so much more uniform in its "shredded-ness". They are both purpureas. Something is different in the expression of the mutation between these two types.

Ron I don't know if it's the same plant .. I have 3 plants growing in the same pot so it's hard to untangle who's who.

I love the picture of the anthers and pistil with the red shift. You can clearly see anthers in the foreground that have not opened yet and released the pollen. Until I started doing these close ups, I didn't realize that anthers opened.

Beth, I was wondering too about the consistency of shreddedness. My Gypsy Bride never threw anything but nice densly shredded blooms.

I have gotten Sunrise Serenade from 3 different sources and they all had variation in the amount of "shredded-ness" of the blooms, so I am thinking it is a characteristic of the cultivar.

Just adding 2 cents about another shredded, double Ipomoea purpurea: Indigo Feathers. The flowers have never been round - always shredded. But they do vary between being single and double on any one vine.

The times when singles have appeared among the doubles on the same vines have been 1) toward the end of a dry spell (after rain, they all went double again) and 2) the vines looked like they were winding up their flowering, so I cut off all the open pollinated seeds and unwound the new growth at the tips of the vines, and consistent production of double shredded flowers picked right up.

So, with Indigo Feathers, stress seems to play a role in the appearance of single blooms among the doubles, here.

I wonder if color might have something to do with it? Some traits seem to go with each other. Could the color for red/fuchsia be linked somehow to inconsistently appearing shredded doubles and so forth?

That round one was the first I had seen, the rest were mostly split with a few shredded here and there.

There's a word used in genetics that means "subject to change": mutable. So, searching for mutable + "morning glory" in www.google.com yields some interesting stuff on a mutable gene for patterns like flake or speckled. Did not see anything about a mutable gene affecting shape. But am too wrecked from today's pursuits to pursue this right now.

very interesting, X - I'll be ba-ack
