Re: tax help - commercial names

Chris, thanks for the info. I have always used the RHS database at:
rather than the Plantfinder. This will be very handy. Does it contain everything in the book? I see the 2006-7 edition is available, but if it is all online I won't need to buy it.

Subject: Re: [CHAT] tax help - commercial names

Can anyone help me out with a website that might list commercial plant
For example, there is a new Clematis out called Clematis Crystal Fountain
(TM). That is a commercial name, not the actual cultivar name, which is
Clematis 'Fairy Blue'. Commercial names aren't allowed to use quote marks.
Like Rosa Knock Out is really Rosa 'Radrazz'

But of course most things we read have not been scrutinized for taxonomical
correctness. So how do I know if I'm dealing with a commercial or cultivar
name? So far, my best reference is the RHS Plantfinder 2005-6, but not
everything is in there and the print is so tiny, and they listed R.
Knockout's real name as R. 'Daddler' - where'd that come from?

Anyway, does anyone have an easier source I can use?
Well, there's always the US Patent and Trademark Office.


But it's not very useful for non-unique names like Knock Out [TM] and it
doesn't turn up Crystal Fountain, but it does find others like Cardinal
Candy viburnum.

When I have a name I usually search the RHS database (also at


) or do a Google search.

The tricky thing is that a trademark can be created by just about anyone,
so there's no requirement for it to be registered in a central location.
Those are registered trademarks (the little R in a circle symbol).

I know, that doesn't help.  :)
