After reading the links another time: seems like the artevos-Website contains an error. They say “The ancestor ‘Apistars’ was already known in Roman times …”
As far as I know this is wrong. The ancestor was “Sternapi”, or “Api etoile”, (it is still available in some nurseries), you can find this information in the wikipedia-article (only german, sorry). And here: https://www.haeberli-beeren.ch/de/produkt/oktober/331/apistar
Also, “Apistar” seems to be a registered trademark. So this is the name of the new, presumably improved variety.
That’s a pity. I don’t think that Api Star, Api Étoilé or any other variety with this fruit shape is available in Canada, I’d have loved to play with some of its seedlings.
Unless the Canadians are better at catching things coming through the mail unpermitted than they are at a lot of other things, you can probably get things from the USA.
I’m familiar some Ohio and Kentucky and Tennessee nurserymen that got things from Europe and Asia and never got the stuff quarrantined. It might be interesting to know the percentages…just as it’d be interesting to know just what portion of illegal drugs are confiscated and the portion that sneaks in undetected.
