Hey Mike... I totally understand you as we seem to suffer from the same problem...
but I intend to keep collecting Eugenias sp. until there are no more to collect... and the good thing in this family is that there's always some new family member coming to light in Brasil or somewhere... it seems a never ending collection!
Just my two cents on this discussion:
Even the bigger ones like E. florida and E. myrciantes are able to fruit in pots in just 3 to 5 years, so why don't you wait to try the fruits before deciding what to plant in the ground?... this is in fact how I decide the species that deserve a permanent spot in my GH... I tend to see my GH as a 5 stars resort for plants
... but there are no free lunches anywhere and only those guests that pay the land lord are authorized to stay longer, because the land lord needs to eat also
... but I'm a very patient and comprehensive land lord
... I even accept a lot of different currencies for payment (fruits, flowers, leaves, roots, seeds, etc)... as long as they pay, they are allowed to stay
The smaller ones are even faster fruiting so it's even easier to choose the best ones during the pot stage... on this class I recommend you skip Eugenia anomala because it tastes like garlic...
But I don't see the Eugenia calycina on your list... big fail!... this one is a permanent resident on my 5 stars hotel!
I'm still waiting to decide if E. speciosa and E. blasthanta deserve a permanent spot or not... sooner or latter I will report on these ones!... haven't decided yet on E. negrense too because birds did not let me try until now!
Keep collecting and good luck!
