I know someone (on this forum) who got his first fruit from a plant originating from these seeds. He said it was no different in size from the standard megalanthus, but wanted to wait another season in the hope that the fruit might get better.
I am not optimistic.
Carlos also told me that the giant Peruvian was naturally thornless, however I think this is another lie. Basically, Carlos has just been selling seeds of fruit imported from Peru, which probably just had the thorns manually removed. Carlos said he is growing it himself, but never uploaded a single photo and won't sell a cutting even though that would maintain the true-to-typeness. Then there is the problem of hybridization, either from Peru or from Carlos (who told me he grows 30 cultivars). He doesn't respond to any of these issues raised ~ just keeps accepting orders and sending out seeds.
