I am searching for an SP Urban.
Does anyone in Europe have budwood or even better a plant to share?
Thank you very much!

Well done! Let`s hope for a short juvenility.

Cold Hardy Citrus / Re: The eremo- hybrids, which ones are worth it?
« on: October 10, 2023, 08:44:44 AM »
what about this one?
https://bluewood.yo.fr/produit/eremomandarine-hybride-satsuma-eremocitrus/
in the picture there is a label glauca x Shekwasha, so nothing special. But the description says Hybrid of satsuma-eremocitrus.
The label that comes with the plant says Eremosatsuma.
Who can help?

Cold Hardy Citrus / Re: F2 citrange winter hardiness trial
« on: September 19, 2023, 03:14:57 PM »Hi Mikkel,Hi Ilya,
An interesting observation. How old was citrumelo rootstock?
it is a probably 3 years old rootstock. I assume it is polyploid. It grows very fast, has leathery leaves and serrated leaf margins. I think it is a Swingle seedling, but i am not sure.
It is 1,50 m high and has already formed a crown on its own, which is probably very helpful. So it may be a simple coincidence, but I want to test it further.

« on: September 19, 2023, 08:33:28 AM »
Hello Ilya, I grafted a mature IchangStar 60 budwood into the crown of a 3 year old Citrumelo seedling, in spring the IchangStar 60 budwood started flowering and so did the Citrumelo shortly afterwards. This may be a coincidence, but I repeat this experiment, let`s see what happens next spring. I come to it because you write about the 100 5starXDunstan seedlings.... Could be a long time to wait for these to flower....

« on: September 12, 2023, 03:03:08 PM »Walt, my "Holy Grail" would be a zygotic Conestoga series tree.In my experience, pollination by Ichang Papeda often resulted in zygotic seeds. even in otherwise nucellar varieties. (But this is only anecdotal and not confirmed!).

Temperate Fruit Discussion / Re: Loquat blooming in summer
« on: September 11, 2023, 05:32:13 PM »
Is it a certain variety? Summer flowering is a rarity in loquats. Only in some varieties this is the case.

Temperate Fruit Discussion / Re: Hardy passion fruit / maypop
« on: September 11, 2023, 05:28:07 PM »One green world in Portland has some really great maypop varieties. I got a bluePop from them last year, it flowered a bunch but didn't set fruit.
https://onegreenworld.com/product-category/vines/passiflora/
Judged by the flower, BluePop is probably a hybrid of incarnata and caerulea. These are often sterile and rarely form fruits, and when they do, they are often hollow.
In any case, you need a second variety for pollination to have a chance of fruit.

Cold Hardy Citrus / Re: US-802 citrumelo
« on: August 10, 2023, 05:29:44 PM »
looking at these pictures I had the idea it might be a polyploid.
https://idtools.org/citrus_id/index.cfm?packageID=1179&entityID=8884
I have a polyploid citrumelo chance seedling that grows like crazy. Even in my climate.
Anyway, if 802 is from Siamese Sweet, it sounds interesting for breeding. But I rather suspect that it is a standard Siamese offspring (but that's just an idea I had when I read about it on the internet).
Probably hard to get? or can you order it from UCR?

Do they bloom as quickly in Paris as in the south?
I have never had a flowering plant. Neither as a seedling nor as a graft.

« on: May 26, 2023, 05:12:21 PM »
I have 3 varieties of these Eremo hybrids. None has flowered in the last few years. At least for me it is a dead end for breeding.

Cold Hardy Citrus / Re: Table of citrus cold hardiness and %zygotic seed
« on: May 26, 2023, 05:09:46 PM »In my experience the proportion of zygotic seeds in partially nucellar varieties also depends on the pollinizator.Ichang Papeda as pollen donor often leads to zygotic offspring, at least in my experience.

« on: May 25, 2023, 03:08:14 PM »
I read the article, but I am not sure if silicone is in english the same as in german...
Is there a chemical/sientific name of it?
Silicone in german is something you use to groute the tile in bathrooms.
