Jalvanica sounds like a code name, so I did some digging, and it seems like a robert Jelly codename of JEL.
This patent by the Hill Co., which sold his creations, also lists JELvanica:
patents.google.com/patent/USPP5635P/en
In an Israeli data sheet, both JELvanica and the rose bred from it are listed next to Jelly and Meilland roses, so there is likely some association, but no concrete proof, other than they list no parents for JELvanica, except that was released the same year as 'Parfait', JELcondir, and JELrandoli, which was 1977. They state their source as ILARO, but I don't know what that stands for. Another Israeli publication from the govt. states ILARO is the name of a holder. Maybe that means who owns the rights for release in Israel. I'm not sure, but it seems to relate to the floral industry.
Is Bob Jelly the same as Robert Jelly? Seems likely.

According to the Israeli records ILARO is the abbreviation for "The State of Israel, Ministry of Agriculture & Rural Development, Agricultural Research Organization, (ARO), The Volcani Center" in Beit Dagan, IL being the country abbreviation for Israel.

Please add to References. From: Bulletin de Societe Nationale d'Acclimation de France, Series 4, Volume 11, 1885, p. 106-107.
"Rosa Microphylla has several varieties: a variety with single flowers, pink, that Phonzo-Zoufou marks under the name of "Kin Ossi." Doctor Savatier found it grown in Tokyo, in the garden of Oya Kouyen. Another variety with double flowers bears the name of "Sansio bara," according to Phonzo-Zoufou.

Single Kin Ossi. Double Sansio bara..... Blindly, without understanding, I have added the reference.

I'm writing an extensive article about the microphylla family. There is a lot of contradictory information in print. There is a source from The City of Sakura Rose Garden with an article entitled "Wild Roses of Japan," by Yuki Mikanagi, Ph. D. In it he refers to the rose as R. hirtula (Regel) Nakai referencing a Japanese publication, Bot. Mag. Tokyo 34:14 (1920). I have found a source by Nakai (Japanese botanist) and in it, if I'm reading the Latin correctly, he refers to hirtula as "Sansho-bara." Very confusing.
However, the first source I quoted was written in 1885 and would seem to have precedence. I'd love to be able to correspond with someone from Japan.

"`KORgeriora` is a seedling selection which resulted from the controlled pollination of Rosa hybrida `KORaruli` (U.S. Plant Pat. No. 22,352), the seed parent, and Rosa hybrida `KORfocgri` (U.S. Plant Pat. No. 22,353), the pollen parent, during the summer of 2006. As part of a rose development program, Tim-Hermann Kordes germinated seeds from the aforementioned hybridization during the following winter and conducted evaluations and observations on the resulting seedlings in a controlled environment in Klein Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant in May of 2007 from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety was given the name `KORgeriora`. " -US PP29,500

I wish Kordes had sold this one instead of Firebird. I was so excited to get Firebird, and it was a massive failure. It grew so much, about up to my face, and bloomed a lot. And within one day, the blooms became very gross. I waited to see its summer bloom. Even worse.
Very healthy train wreck. I tried nuking it with Roundup. It grew back lol. Need to dig it out this winter.
I thought it would be like Sunbeam Veranda or Mango Veranda, but no, this was a skyscraper with cream, puke red, and decaying brown petals lol.
Orangerie woulda been a better choice for intro :[ Or anything fun and not a tragic mess....

In the HMF description of this rose, I see that they say "Feed this rose well". This rather confuses me: it's a Found Rose, after all, which gives the idea that it does fine with little fuss. Am I misssing something? Can anyone throw any light on this question?

In general, most Hybrid Perpetuals with heavy Damask Perpetual ancestry (as opposed to those more Bourbon-like, and the later ones with more Tea in them) do need to be "fed well" in order to keep "blooming well", but will "live well" just fine without. From what I've come to learn after growing them, they bloom when "late Spring conditions" -- milder weather, and an influx of water and nutrients -- trigger new growth. A prune after flowering helps as well. In the meantime, they hang in there and survive just fine once established, even if they don't bloom.
