Q: What are cultivar-groups?

Mars
Drosera capensis 'Mars'

Othello
Darlingtonia 'Othello'

A: Cultivar-groups are, well, groups of cultivars! Let me give you some (fake) examples. Suppose you were a hybridizer of Sarracenia, and were working on developing hybrids with marvelously frilly lids. You developed a hybrid that was so nice you established it as a cultivar named Sarracenia 'Frilly Willy'. Then, suppose later on you developed another cultivar that you called Sarracenia 'Compact Crenelations.' Suppose you wanted to note that both these cultivars are part of your program of frilly-lid hybridization. You could register the name of a "cultivar-group" just as you registered your cultivar names. (For the sake of our fantasy, let us say you called it the Wavy Wonder cultivar-group.)

If, later, you made another frilly lidded hybrid that fit this group, you could note that it should also be considered part of the Wavy Wonder cultivar group. If you called this new plant Sarracenia 'Wide Wiggles' you would have three members of this cultivar-group, namely:
Sarracenia (Wavy Wonder Group) 'Frilly Willy'
Sarracenia (Wavy Wonder Group) 'Compact Crenelations'
Sarracenia (Wavy Wonder Group) 'Wide Wiggles'

You could also write them as:
Sarracenia 'Frilly Willy' (Wavy Wonder Group)
Sarracenia 'Compact Crenelations' (Wavy Wonder Group)
Sarracenia 'Wide Wiggles' (Wavy Wonder Group)

You register cultivar-group names with The International Carnivorous Plant Society just as you register cultivar names. Go to the home page for the International Carnivorous Plant Society and download registration forms and instructions.

A few other notes about cultivar-groups. A plant can belong to more than one cultivar groups. So if your Sarracenia 'Compact Crenelations' is a dwarfed plant, you could specify it is also a member of the Dwarf cultivar-group, if such a cultivar-group existed. Also, depending upon how broadly you define a cultivar group, someone else could add a cultivar to "your" cultivar group. So do not get too proprietary about the names!

A real-life example of a carnivorous plant cultivar group is the Dentate Traps cultivar group for Dionaea. This cultivar group includes all the Dionaea cultivars that have shortened, triangular teeth, such as Dionaea 'Dentate Traps', Dionaea 'Sawtooth', and Dionaea 'Red Piranha'.
