What species takes the longest to flower from seed?

For the sake of conversation...

I once read of some SA amaryllid (Boophone, maybe?) that took around 15 years to flower from seed. I wonder, what is the longest time it has taken a bulb to flower from seed?

I'd also be curious what the evolutionary advantages of such a long wait before flowering are? I understand how for an annual plant, reproduction is of higher priority than survival. With the long lived bulbs (and trees and shrubs, I guess) mere survival trumps reproduction. What are the driving factors, environment? Availability/type of pollinators?
