Yes, it's more rare than those.
Look at the amp color forms that are available now. Yes, they are all amps and three are red amps, but a new Cantley's is around $75, a tricolor is $130 or so, and a Williams is double that.
Look at Sarracenia when a new flower color is found. The leaves may look identical, but or that month it flowers, boy oh boy, I gotta have one of dem!
Everyone has different opinions on what they like and so0me may think 'Scarlet Splash' is a "must have" and some do not care for any hybrids and not even remotely be interested.
