Hi Sandi,
some months ago I found out that there are a lot of cultivars from André Smits (BE) with the "Zilver" in front; the same names are at SMG without breeder-informations but the "Silver" in front;
I decided to ask SMG but I forgot it for a long time
now this question is reactivated....but I have no contact person at SMG;
in the next days I will search for all the mentioned Zilvers;
