Luc,
I grow them I find them to be sloooow, specially the first few years! One new leaf now and then! I also grow bacupari miudo (garcinia brasiliensis) and this one is not in a hurry, at all! Extra sloooooooooooooow in the juvenile stage! However, when they become adult, it is everbearing. My friend has a tree and every time I see it, it has flowers and ripe fruit hanging all year around, here in Fort Myers.
