That must be it!!!
Seriously, though, when I went back to check my info regarding temps, I read:

Winter days average 53-56F (12-13C), and nights average 37-40F (3-4C), with a diurnal range of 16F (9C). We do not know if winter temperatures really need to be this cold, but nighttime averages should probably drop to near 40F (4C) for 2-3 months. In Korea, even the most moderate locations near sea level at the southern tip of the peninsula have minimum temperatures that average below freezing for 2-3 months in winter.

Mine isn't getting that cold!! But it is still cool, min of below 50F/10C. I remember some discussion before buying this plant - when it was brought up as a possible project plant - that many plants are short lived. I think it was Sue who pointed this out?? So I looked into it some more before buying and found this bit of info:

Christenson (1995) reported that plants of this species are relatively short-lived in cultivation, usually flowering no more than 4-5 seasons. It is more likely that these plants need a cold period to become dormant and receive the necessary rest. If winter temperatures are too warm, they simply continue to grow until they die from exhaustion.

So, I'm happy for mine to grow and flower in its own time!
