I have one plant bought I think in 2004 or 2005. It is a good size plant by now, doesn't say peep. Now sometimes one does pick up a dud, so I bought another plant from Andy in the Spring. This one turned out to be a lot smaller than my older plant, so I probably have to wait another few years for that one to bloom.
I don't think it gets enough of a cool rest in my care, so that may be the problem?
