Product Review (submitted on June 17, 2012):
The Royal Red that I bought doesn't seem to be as vigorous as my other red varieties - the Pink Venus, the Red Piranha, and especially the Akai Ryu. All of those red cultivars seem to be more vigorous and produce larger traps and more traps than the Royal Red. There seems to be some mixed reviews about Akai Ryu on the internet too - some people say it's a weak form, but for me it grows very vigorously.
Getting back to the Royal Red. I've only had mine for about a year, so perhaps it still needs to grow out a bit more. Comparing it to the Akai Ryu in coloration, the Royal Red is supposed to be more red, whereas the Askai Ryu is a darker shade (some people say almost purple or even black).
Royal Red has not propagated for me from the rhizome yet (the Pink Venus, the Red Piranha and have produced a lot of little plantlets).
