I had that kind of trouble with "Beauverdia sellowiana", the 
ipheion-like plant with bright yellow flowers having their floral parts 
in fours. The pot was exposed to low temperatures (not low enough to 
turn any of the bulbs into mush), which apparently forced the bulbs into 
a deep dormancy.

The cure was to expose the entire pot to considerable warmth by just 
letting it bake in the sun, which led to the bulbs sending up new growth 
for the first time in several years.

I hypothesize that this behavior evolved in a hot climate that once in a 
long while gets a cold snap. The bulbs go dormant as protection from 
cold, but don't start growing again until heat says "it's over, it's 
safe now to grow actively again." Pure speculation, of course.

PS: Beauverdia sellowiana has another name now, but I'm too lazy to 
track it down.
