I have one of these, much younger than yours. It isn't the most reliable bloomer, though. I suppose these are a tad easier to grow in tropical areas, but I thought they needed a decent drop in night temps to bloom? My plant grows well and doesn't seem too demanding, but it skips blooming some years for unknown reasons.
I like the flowers on these, particularly the fragrance. They smell (to me) like Pez candy. Nice, light, and a bit fruity.
