Mark, I just wrote what was told to me by Eric Breed.
I have no reason to doubt about his kwowledge.
but I know that changing names in the trade is very usual,
in this case the name Rijnvelds Early Sensation was not a good seller
in the USA and UK.
I give you a.o an other example:
In my younger years a grew a lot of Delphinium Andenken an
August Koeneman, but my customers were always seeking for
Delphinium Wendy, because they needed it for export to the UK.
(mostly they did not even know about the right name!!)
Greetings, Luit
