My Fragile Moments died last winter too, Dave. I think it is just too fragile a bush! We have customers who have old ones that are really tough, like Charlie's stock plants. So I guess if it makes it through the first few years, then it develops more vigor. But instead of working on it any more, we're working on replacing it with a similar pink double with a better bush.
Pink Delicious that we already have is much more vigorous than Fragile Moments, and it has the softer pink color too. Plus its flowers last up to 5 days - amazingly long for hibiscus.
We also have this new one coming up, Goodbye Girl:

It's a brighter pink than Fragile Moments, and the flower has a heavier texture, more like Lady in Waiting. But it's an amazingly good bloomer! Look at this:
