Rose leaf cuttings??

9 years ago

Well, this is interesting.

It's a leaflet of Raindrops. It fell from the actual rooted cutting of it into the peat and apparently made its own roots. No idea how long it took it nor how long it has been like that. Should be less than a month.

My guess would be that it may be a very, very, very short stem? Like, those that just jut out a millimeter and then develop a leaflet or a set of 3 and then do nothing at all, ever. No idea why it would fall then, tho.

Has this happened to anyone? Do you think it'll eventually be able to form a stem, be viable etc.? I've carefully covered it with some more peat, just for fun.

I've rooted a lot of things from leaves, but I've never even heard it was possible with a rose. There almost had to be a few cells of stem/bud material included, because that's where the undifferentiated cells that can become roots are found. It's almost like you accidentally made a meristem cell culture, the method they use for mass cloning. VERY interesting and it would be worth some research to find out just how easy/difficult this might be when done on purpose. I hope the leaf truly roots and forms a plant. It would be so cool...

Edit: I hope Kim (roseseek) chimes in on this. He might have a better idea of how this would work.

Rosacea,

Fascinating! Never happened in any of my propagation projects. Please keep us posted on the progress of "Wonder Leaf."

Ha! that is so cool. I didn't think it was possible but you know, "Nature finds a way".

Yeah, John, that's what I was trying to say in the post, that perhaps there was some bit of growth ring or something attached, perhaps intercalary meristem? I don't remember if this was just a single leaflet when attached or if it was part of a full compund leaf.

It made me think of meristem culture too! I know people who manage to propagate their orchids that way at home, but of course, they have the necessary scholarship of it. It would be cool if we could do that for roses.

But as far as I'm aware they don't use leaves for that. I think it's tiny bits of stem where active growing cells are present. Though there's more than one way of doing it, I'd think. I don't know much about the topic, you may notice, haha. I do think it's super interesting though! And I'm crossing my fingers for it to become a plant too!

Will keep you all updated!

Seriously? Well, at least I can offer you congratulations..... even as I grumble. spend lots of time and money on trying to get cuttings to take. And I never have any luck. But glad for you.

Congratulations! Though I've not done this, I can see where it could happen. As Ralph Moore always said, "The rose will find the way!" You lucked out with all conditions just right for the tissues to differentiate into what is necessary for roots rather than rotting. The trick is going to be figuring out how you accomplished it, then being able to repeat it! Good luck!
