Yes they have and it's the only one. The stock is from 3 years ago when someone went to the jungle and collected them. I expect germination to drop to 5-15%, without the help of chemicals. Other vasconcellea have 0-5% germination rate unless germinated in vitro.
Thanks, Lebmung.  I can live with that.  Germination has been the easy part with these guys, it's keeping them healthy afterward that's problematic for me.

Keep us updated!  :)

Hard to tell what kind of flowers are coming out.

have only this for now:) will be in garden in 2-3 days so will take more picstures, also by that time they should be more emerged now they were really tiny..

Hard to tell what kind of flowers are coming out.

i think they are going to be on the long stalks like the males on other papaya relatives.. but might be wrong lets wait few days..

My V. palandensis has been showing browning tips and necrosis in the tips of leaf tissue.  I'm thinking it's a nutrient deficiency or a root issue maybe? I'm trying not to over water it but maybe I am under watering it? The soil it's in is fairly moist and was receiving shade around the base until a few weeks ago where I gave it a little more exposure.  I also have a fairly high water table, about 2' below soil surface is heavy wet clay. I wonder if this is causing root issues? 
 Anyone have any ideas?

I think my plant is on the bring of pushing a flower cluster.

Wet clay is the sure way to death. Anaerobic bacteria is eating the roots.
This is slow decline because of overwintering. But in a heave clay soil it's impossible to manage the water.
Once cold weather sets in the plant will die.
I suggest you save the plant by airlaying.

The thing is it's late summer here right now. Hasn't had any cold temperatures outside of a pot.

When I say cold I mean nights with a temperature drop to 16.
This species comes from tropical premontane forest at 1800 altitude. The temperature interval is 14-28C. Humid conditions.  The soil structure is high organic material and sandy. It's instant draining. And the most important the microbes from the forest live in symbiosis with the roots.

Hmm, I have kept them outdoors through 0*C temperature and they have done just fine unprotected and fully exposed, albeit, in pots. 

I am thinking of grafting some side shoots onto Babaco.  Has anyone ever grafted Vasconcellea?

Yes I did graft papaya on babaco. Side graft it's easy.
However the roots of babaco are weak as well.
The best rootstock is Chamburo grown from seed. (should you need seeds let me know)

here are more photos of the flower clusters forming, they are still very small.. also the second seedling is starting to form flowers this have a bit purple color, but it might be caused with lower temps.. these two seedlings have same grow habitus the other two seedlings that havent flowered yer are shorter and have more compact growth, also they are already growing side shoots/branches.. so i think this might be a gender difference sign? taller males and compact robust females?














here is the second seedling tiny flower cluster

Nice job you've done, not many Europeans seem to grow them.
The first seem to be male and the second I can tell maybe female. Do you have problems with spidermites? For some reason them love vasconcellea.

thank you, not sure how many europeans do grow these but hopefully there much more so better chances to preserve and save this species! i wish you are right about the second seedling and frmale flower let wait and see..
i do have spidermites problem indoors when i am overwintering my tropical plants.. i still do not know how i will be overwintering these if in cool/cold room or in warm.. as in warm they would need lot of light in cold they might go dormant but could get root rot..

Does anyone have experience doing Tissue culture on vasconcellea/carica? I just found out I have complete access to my universities labs/equipment to run my own TC experiments. 

Further, does anyone have suggetsions on best way to propagate V. palandensis? I'm thinking about bridge grafting onto Babaco so I can back up the plant. Has anyone tried air layering?

thanks !

So far there were no experiments on V. palandensis. No protocol published.
Papaya is easy to clone, but Vasconcellea is more difficult. There are few rare TC protocols on V. pubescens and Babaco. Babaco is quite difficult to clone so I suspect V. palandensis to be also. It gets easily damaged by chlorine and it has a high rate of hyperhydricity.
The experiment you want to do it's more like a doctoral thesis. I make TC for bananas, may try to get into cloning Vasconcellea.

Babaco can be used as a root stock, on which papaya can be grafted so I expect V. palandensis to work as well. Here is my experiment https://www.facebook.com/plantetropicale/videos/1172871089402049/
Babaco roots are no so strong as Chamburo grown from seeds so I prefer the later.
Air layering should work also, but I expect the roots to be more sensitive.

Nice job. I am afraid it's a male. Don't kill if someone will have a female and you can share the pollen.

yes i know it will be high probably male. I have 3 more seedlings so hopefully there will be a female.. i think i have two males and two females according to the grow habbit.. both pairs have very different grow habbit.. time will tell

A male indeed, perhaps you can save the pollen or try hybridize with a papaya.

Just dug up my V. palandensis and potted it up. Hopefully it will survive the transplant! I also took a lot of cuttings and I am trying to root them, so hoping for the best. Pretty sure it's a female based on flower rack structure.

Papayas don't transplant well. After the transplant you should not water the plant as it needs time to heal the wounds, also cut the foliage.

Foliage was cut and I watered it after about 4 days of not having been watered.

What is the best way to germinate these? Paper towel, straight to pot? Has anyone done a Gibberellic acid soak? I potted up a few seeds but haven’t seen any come up yet. Been about 3 weeks.
The best time to plant a fruit tree was 20 years ago. The next best time to plant one is now.
