Talking to Adam at FFF he said there are basically two types of calycina tasting notes: one is metallic and gross, the other is pretty pleasant balance of sweet/sour. I feel like the one I have is the sweet/sour. It never really gets pure sweet and definitely isn't as outstanding in flavor as CORG which is kind of papaya flavor when they're a good cultivar.
I have Nelita seedlings from Miguel that will flower this year, and have several other seedlings, along with grafts from Wildlands Nursery and Achetadomestica. I hope to find a real winner from this bunch.
This particular fruit shown here is much fatter than other calycinas I've seen and I am curious if it's a hybrid between CORG and Calcyina which I believe happens a LOT. I know for sure mine are cross pollinated by my CORG which only a few feet away.
Calycina and CORG definitely need more selected and named varieties.
