Mines are still tiny, and long way from flowering. Maybe 3-5 years? The longest leaf (not leaf span) is 7-9", and each of them has a single growth. But they were at a reasonable price ($18.75 each). 10 years ago, I paid $65 for 2" leaf span, which I managed to kill within a year. The price of seedling P. sanderianum has been getting pretty reasonable.
