Cordyline indivisa x australis experiment
Hi all
Am beyond excitement that the experiment I started back in late Spring is showing tangeable results. You may remember when my C. indivisa tree (for I now call it a tree, and not a mere plant) flowered and set seed, I saved some pollen from it and hand pollinated my C. australis (trees).
The resultant seed was collected and sown and I'm pleased to announce the arrival of 5 young Cordylines with, I think, more to follow.
I've found the secret to germination of indivisa seed along the way too. I can get seeds germinated in 3 weeks with a lot of bottom heat. I now put the pots of sown seed on top of a radiator that gets quite hot, they seem to like this and spring up like grass (slight poetic licence there!).
It's still early days for these seedlings and until they get their true leaves I won't really know what's happening, but I do remember being very careful about cross pollination from other australis flowers so I'm 99% sure these are true indivisa x australis plants. I will update this post when I get them to the true leaf stage.
Still got lots of pure indivisa seed left if anyone's interested.
Regards
Adrian

Great hybrid. Please update us as the seedlings grow up.

Re: Cordyline indivisa x australis experiment
Any news on the seedlings?

Re: Cordyline indivisa x australis experiment
As the old nursery rhyme goes: "And then there were four", one seedling has perished due to damping off I suspect. The other four are doing ok, but not a lot of change pictorially.
I've removed them from their plastic bag propagator now to toughen them up slightly. I will update the forum when there is significant news.
I'm wondering if anyone else has had success with the hybrid seeds I sent out? Please let us know.

Re: Cordyline indivisa x australis experiment
"And then there was one"...........Only one of my C.australis x C.indivisa plants has survived. I'd be pleased to know what anyone thinks with regard to the resultant seedling's characteristics (and if they concur with what I think).
It's growing strongly and putting down an areial root from the growing point: as yet I cant see any orange stripe down the leaf, but it might be early days for that, the leaflet does seem quite broad (which is hopeful).
As I said, I would be very grateful for yout thoughts on it......please don't spare my feelings, be honest.
The small aerial root can be seen in this picture.
And this is the plant at a distance.

Re: Cordyline indivisa x australis experiment
Adrian... I am puzzled by the distance the base of the plant is away from the soil. Is the main anchor root causing this effect as it sometimes happens with palms in pots?

Re: Cordyline indivisa x australis experiment
Andy, it's exactly the way some young palms grow in pots. Most odd (to me) but I suppose it's pretty normal, when it's a larger specimen I shall re-pot it up to the hilt as it were, but as it seems happy to grow like this I am leaving it alone (it's still in a plastic bag propagator).
It's interesting to see the start of a glaucous covering to the tiny stem, which indicates an indivisa gene to me, but then again I could be totally wrong as australis might grow the same way (I can't remember).

Re: Cordyline indivisa x australis experiment
OK, so I'm not giving up on this!
This cross indivisa / australis seems to grow at a prodigious rate, I thought I'd take a few pictures with my phone today.............you'll see it has a white / translucent edge to the leaf and also the start of an orange midrib (very indivisa) but also I think there are going to be other orange stripes down the leaf too. Tell me what you think? Oh and there's a glaucous bloom to the undersides of the leaves which doesn't show well in these pictures (also very indivisa IMHO)
Aerial view:
Side view:
Side view 2:
Currently the leaves are just as wide as the pure Cordyline indivisa seedlings I have coming along, which is hopeful too. This is the only plant I have left although I did send out some seeds from this C. indivisa x australis experiment to many of the people who asked me for indivisa seed.........Have any of you had luck with germinating them??

Re: Cordyline indivisa x australis experiment
Adrian its a bit difficult to tell from your photos as they are a bit hazy however to soil they are growing in is crystal clear and looks really good...
