Hi Everyone!
Joe, it is a good idea to know a plant's parentage, but to register a cultivar it is not required. N. 'Savana Rose' is actually a red pitchered form of the hybrid N. emmarene (khasiana x ventricosa). We have a beautiful cultivar (a selected clone from amongst the many siblings) from Clyde B. of N. Rokko x 'Savana Rose' that Michelle just took cuttings on. C. Bak and 'Miranda' will no doubt make excellent fathers in the future as well.
Owen brings up some good and often confused points. N. Corn.bak, Velvet, Gentle, if not all the same clone, come from the same seed pod. N. 'Miranda' is a distinctly different hybrid, belonging to the Mixta Group. It is not pure Mixta, which is (maxima x northiana). Mixta 'Superba' is male.(By the way, female clones of true N. Mixta are extremely rare. There was once a clone called N. Mixta 'Sanguinea', a real beauty, that was female, but I have not been able to locate it-anyone have it or know of it
) In order to derive any seed to put into tc it must be crossed onto a female. A female maxima was used to do this. The cross of N. maxima x N. Mixta has been done before in Japan as N. Oiso. N. Oiso looks just like N. Miranda, to further verify the likely parantage or N. 'Miranda'. N. 'Miranda' is not a registered cultivar, as no description has ever been published, even though it meets all the criteria of a cultivar otherwise-ie. it is a single clone of unique character (even though it looks a lot like N. Oiso and N. Mixta).
The color variations described by the French site are purely cultural differences. Our 'Miranda' s consistently produce huge Mixta-like traps that give off a wonderful sweet aroma on hot, sunny days.
