Why is it better than other Garcinia species is a great question. Because it looks better appears to be the answer you’re getting.
They are the 1 African Garcinia species and are quite different in a couple ways.
1. Appearance
2. Drought tolerance
3. Can be kept as a small hedge
Flavor wise and flesh to seed I don’t think they rank in the top 10 personally but I believe some people have tried sweeter and less sour kinds then I have.
I still like the flavor and grow them, but in a relatively dryer climate where other Garcinia are not thriving but the Imbe’s always look great.
I think 5-7 years to fruit in a marginal climate is hopeful thinking but maybe not impossible.
A question - I don't have any garcinia yet, and I have been looking into the best species - what is so good about Imbe?
Why is it better than other species?
