The natural wild type Ipomoea nil is a funnel shaped flower, blue colored, and dark green 3 point leaf shape. All the other Ipomoea nil cultivars we grow are mutants from the wild type. The traits you asked about are brought about by various gene mutations. I am not conversant in morning glory genetics; however, I find it fascinating and learn by growing the plants.

Thank you for the explanation, Joseph. I just looked at them, as cultivars & then thought, the actual "mutant" variety, are those with unusual flower "shapes", such as "Double" or feathered & mutation of leaf "forms", like dragon, or willow... At least, that was my take on some of what I had read about them, online. I suppose, if observed enough, you may be able to predict, with a little certainty, what type of flower you may get, from some of what I consider to be a "mutation". But it could be just simply a matter of semantics & will try to learn, as I watch them grow & flower.
Today, was 'Chocolate' !

I found it to be rather interesting, that these would actually flower, while really rather quite small, when compared to what I've grown in the past. Do you keep any notes , in particular, about some of the varieties? Or just try to label them, to keep track of seed names, for collecting ? My memory isn't quite what it used to be !

I put an ID tag in each container and collect seeds separately, not mixed. Other than that, I don't take notes except when I started a perennial plant.

You can predict with some certainty a kikyo flower will appear based on a character of overlapping lobes at the base of the leaf. Sometimes you can predict the color of the flower based on the color of the hypocotyl tissue. The gnarly shape of the cotyledons is an indicator the plant will be different. Any plant with way different leaves quite possibly could have a different flower. Perhaps more predictors exist that other members can offer.

I will have to try & pay attention, to some of the details I noticed were different, with some, as you mentioned & see what arises, from unusual cotyledons & such. I tried to see if the "Speckled" had any spots on the young seedling stem, for instance & didn't notice any, with what grew.
But as time goes by, I may be able to recognize some traits, from various differences.
I figure some are different, just by nature of the seed color, being dark, or pale. Just to start with & some have more variegation than others, of the cotyledons, yet seem plain green, when growing first true leaves..
I suppose, it will take some time, before learning the variations & what they tend to produce, in the way of different flowers. I will have to take a look, about the 'kikyo' trait.

Here is a photo of Blue Silk Kikyo leaves.

I have heard from others you could determine speckled flowers by seeing speckles in the hypocotyl. I haven't looked at that one yet bur maybe it's true for some cultivars.

Unfortunately I couldn't find my Ukigumo seeds. I'll keep looking. I have another one growing that should satisfy my craving for Robin's egg blue colored flowers.

Care to have a 'Chocolate', anyone? The picotee edge didn't show, much, but it's there...

Apparently, I liked 'Blue Silk', so much that I must have sown, as much as I could, of those seeds ! But may not be kikyo. Had some Sazanami #1 sprout & waiting on some with pale seeds, as 'Ukigumo', but this one, is supposed to be dark seeds. The Cotyledons are pale, to varieagated & a slug ate nearly all, except one. Though had some more in the packet to try again & as it was likely rather old seeds, but just one has swollen up, after about two weeks.The AC may be slowing germination...

You have had your share of plagues this spring.

Lots of winds, from the West, & was drought like this spring. Can't complain about the sunshine, though that tended to really heat things up, early. Hope you find 'Ukigumo' wherever you placed those seeds. The 'Keiryu', will have to do, as a "substitute" for any 'Ukigumo' ! At least this year, here.
I didn't really expect any slugs, at all, with as hot as it gets, on the Southwest corner, so closely near the house. Will have to check for any more late straggler seed sprouts. Before it gets really hot once, again.

Here's a seedling of Ipomoea nil 'Sazanami' that has more chlorophyll in its cotyledons than the previous 2 that were pure yellow and failed. I hope it grows well.

Gerris2 said:These plants of a mutant line of Japanese Ipomoea nil are ready to party.

I'm hoping to see this botan flower form in one of the 3 plants shown above.

That is a beautiful bloom, Joseph!

I grew some dark seed of 'Sazanami' (#1) from Ronnie. Can't recall , if they were quite that yellow. But, I sprout mine in baggy with moist coffee filter, first. Then pot up & place in some direct sun & shade. Those are now normal green, ( may have started out, pale?) with with darker red stems, now. While a packet, as "Ukigumo" the seed was (rather old ) & 'entirely pale seeds. Yet 'Sazanami' was on the other packet, with one pale seed & all other seedlings stems are dark in color, now.
What the slugs didn't finish in the way of the seedling stems, are now still green, but just planted a seedling again, from this so called "Ukigumo" packet & have two, now.
I only got the one, which seems to stay small, possibly (#2) 'Sazanami',as the description on packet stated, as though it may resemble 'Sazanami #2, ( instead of 'Ukigumo' which was what it was labelled as) & the name written on the "trade packet.". Likely from a co-op, some years ago.
It will be nice to see how they all turn out, & won't know for certain, until they do flower. These were variegated/ pale cotyledons. & a couple are green stemmed & the others dark stems now.Tiny, first leaves so far & slow growing...
Except, I trust the packet of 'Sazanami' from Ronnie, is as what it should be.

Joseph, I like the 'double flower' you have, from that "curled edged" leaf ! Will see later, to compare it with. what this one here does.

If you look in the Database, you'll see, the "error" ( #2 Sazanami photos) & a darker color, of what Ronnie posted, in the very start, of this thread. The #2 version, is supposedly pale seeds, while apparently, actual 'Sazanami' ought to have dark seeds. I like both & am just hoping I have both, the "error'"(#2) plus the original.

Now, I do see that the packet "as" , 'Floating Cloud', with variegated cotyledons, has green seedling stems. I left what was remaining of the stems, after the slug had its' last meal, with those cotyledon leaves & hoped the stems just might possibly attempt to start another growing point, somehow or other. Maybe I can find a photo, showing Fukukaen seed packet, depicting the cotyledons of it.

I can't believe, after all of these Japanese morning glory seeds I've got growing, I actually almost bought 'Matsukaze' & decided to order Ukigumo ( Floating Clouds) !
As if I really need more ? Oh well, happy JMG growing !

Gotta keep the slugs and wabbits happy.
