I've been pretty obsessed with cocktailing trees the last few years. Below are some of them I've been working on. I'll add a few more photos here as I find them. Eugenia don't play nice with each other for cocktailing, as I've experienced. Even something that is supposedly the same species - involcrata x calycina failed. I don't think I'm bad at grafting, so, I think it's a compatibility issue. Discovering this, I just make cocktails of the same species together but of different "cultivars" or seedlings from different collectors as it is. I need to find a photo of my 4 type CORG and 3 type calycina. They've all healed nicely and are quite big. I do this mostly for cross pollination, but also so I can sample other varieties (they fruit in the 2nd year after grafting) to see how the varieties stack up.
See below:
Santa Barbara peach rootstock with: apriums, cherries, pluots, plums, necatplums, peaches and nectarines


Jaboticaba with 15 types or something, I should probably count

A plum rootstock with the same list above (different location)

Apple tree with 11 types

8 type citrus on inedible pomelo rootstock, I need to fill in the middle still as it water sprouts
