It's been 10 months, and my leaf cuttings are still looking good but show no signs of rooting or new growth. I've rooted multiple stem cuttings in the same time though and they seem easy but slow, taking 3-4 months to root.
After more than a year of teasing me with flowers and aborted fruits, one of my plants finally ripened a fruit:
Sorry for the weird colors; the leaves are a nice dark green but cameras just don't take good pictures under my LED lights. The fruit was actually quite good, with a perfect sweet / tart balance and a pseudo-cherry taste with a small spherical seed; easily the best Eugenia I've had so far (but I've only tasted 2 others) and about as good as a good Bing cherry, though with a slightly different flavor. I'd certainly give this cultivar from Logee's a thumbs-up.
Both my plants are about 2 feet tall and wide and have a lot of flowers at the moment so hopefully I'll get more fruit soon!
