I wanted to add this one, but it appears that the system has it as an AKA with another trademark name: Caliente® Deep Red. I see Calliope Scarlet Fire is there, but not Calliope Dark Red

Hang on Joanne, I tried to add this as a new entry, Pelargonium genus, Calliope® Dark Red as the trade name, I didn't enter the cultivar name because I can't find one so far.
Dave, need to know how to proceed as I can't enter it without a cultivar name.

This is a proven winners (who would have guessed?!?)

The cultivar name for this plant is 'Amri Trared'.

Here's the plant breeder website that has the info for all their trademarked varieties, which includes the Calliope series. The Calliopes are Interspecific, which means they are a genetic cross between a Zonal and Ivy. Dummen Red Fox also has some Interspecific varieties Cummbinata Deep Rose and Dark Red

When a cultivar isn't provided but a patent number is, this website can help in finding cultivar names. http://www.ptodirect.com/

ex.
from Syngenta website: Americana® Bright Red http://www.syngentaflowersinc....
PTO Direct search by patent number PP12,106: cultivar name: `Amri Bright Red` http://www.ptodirect.com/Resul...
Be sure to preceed patent number with PP (plant patent).

LOL, I even looked at that Proven Winners page Dave but didn't scroll down enough to see the cultivar name.
Joanne, I had also looked at the site too, which didn't provide the cultivar name. I rad the info on the cross, sounds like great plants!
Good to know info Evan!

If this hasn't been done yet, I can create the entry for Joanne.

Here you go Joanne:
Geranium (Pelargonium Calliope® Dark Red)

Thanks Sue

I notice with the PW website, they often (but not always) put the cultivar name at the very bottom.

Thanks
