In February of this year I ordered a bunch of random seeds from Bellamy. I was poking around my greenhouse today and noticed that one of these had flowers and fruitlets forming, only nine months after planting thje seed.
I hope Kameron won't mind me posting his description here, from

Seeds were imported directly from Brazil. This is thought to be Syzygium sp but it is not for certain. It is a small dense bush, that always stays small. Due to its size, it can stay in a container long term, or maybe even used for bonsai. The plant fruits abundantly, and several times a year. This plant like well-draining soil and lots of sun. The fruits are said to be good and eaten out of hand and are very sweet. Each fruit contains only one seed. Collectors in Brazil have reported that their seedlings are starting to produce after only 2-3 years from seed!"

These particular ones were pre-germinated and most of them sprouted and survived. I don't remember if I tossed the excess or if I have a few more floating around my greenhouse somewhere. I guess it is possible there's another one flowering in my greenhouse and some flies cross-pollinated, but most likely these are just easily self-fruitful.
