the one that I tought it was psidium australe is in fact an hybrid, maybe P. guineense x P. grandifolium (Leslie Landrum told me that): frost resistance is the same and the species grows in the same region as psidium australe. A rare one! Pulp is firmer / crunchier, less gelatinous than that of the common psidium guineense and the taste is sweeter. The plant seems very similar to what you see on the internet in terms of psidium grandifolium.
