The Eureka rose that I have is a Kordes rose. I think the new one from Meilland was re-named because Kordes trademarked the earlier Eureka. From what I can find online, it looks like this is the first year anyone outside of France has offered the Meilland Eureka-"Gold-Struck". It looks like a great new rose.
I really can't fault Meilland for renaming Ines Sastre with a more marketable name. It looks like that rose has a different name in every country. I bought Raspberry Cream Twirl last year when Edmunds first offered it. It's another one that was offered in Europe for a few years before it was introduced here, so that's why the registration dates differ.
