The label that came with my Coreopsis says: Coreopsis TM 'Fools Gold'
I have no idea what that TM stands for?
How do I enter it in the database?
Another thing is that when I google 'Coreopsis Fools Gold' I get images of an entirely different looking plant ?

I feel sure mine must be derived from the specie verticillata. Can I add then the specie name?

The colour is unusual, being white with a dark brown nearly black centre..I cannot find pictures of it on the web..

I believe the TM stands for the 'trade mark' for a patented plant. I don't think you need to include the TM on the database. But I could be wrong.

Joy's right, the TM means trademark. The company is simply stating that they own the cultivar name for this plant.

Leave it out. Enter Coreopsis as the common name and 'Fools Gold' as the cultivar.

Thanks Joy and Dave! Coreopsis 'Fools Gold' it will be!
