Sorry, I'm not in a tropical locale, and I haven't tasted them yet... But I am growing Eugenia reinwardtiana in a container- I got two from Logee's about 13 months ago, probably when Oscar did.
Seems to be very easy to grow, not demanding of fertilizer or sensitive to it, and seems to be happy from half-shade to full sun. They tolerated very low humidity and high winds very well last summer when they were outside, but grew very slowly.
They seem very precocious- mine were 4" tall when I got them last January, and they both bloomed by the end of the summer (August here in Colorado) when they hit about 1 foot tall. A couple fruits formed on each plant, but they aborted when I had to pull them inside for the winter-- they were put in my living room with very little light for 4 months while I was finishing their more ideal winter quarters. Within 2 weeks of being given light and constant warmth (65 at night, 85 during the day), they have matured another 4" flush of growth and are pushing another flush now. To my optimistic eye, they appear to be developing flower buds again as well, but I'll know for sure in a couple weeks.
