The standard photo is published in "The Savage Garden" 1998 page 212. The description: "In my California greenhouse in the summer, hummingbirds frequently make a beeline for our flowering Mexican butterworts, probably because the birds are familiar with pings from their winter sojourn south of the boarder. This sometimes results in seed which I usually destroy, not knowing their pedigree. Once, however, I grew some plants from seed collected from a P. moranensis variety dubiously marked 'Superba'. Some of the resulting plants I sold before maturity, nicknamed "hummingbird mix." Our friend, the namesake of this cultivar, grew one of these plants to flowering size. Its
exceptionally large, full blooms of deep pink petals warranted its preservation. The
oval summer leaves are undulating and virtually marginless."
So the defining characteristics are emphasized above. White pattern on flower has no bearing.
I have a 'John Rizzi' that I got from you several years ago. Is it the same clone as you currently have?
These 3 flowers are on the (as labeled) 'John Rizzi'
Exceptionally large full blooms - check
deep pink petals - ??
oval summer leaves- check
virtually marginless - yes as compared to say D. debbertiana
Here is the flower vs P. laueana × emarginata flower
