I've had a Crinum thaianum growing in a 180 gallon for maybe eight years
now. It produced a similar spike about three months ago. It reached nine
inches or so in height, and then stopped growing halfway to the surface.
The crinum  bulb itself is about three inches in diameter and produces a
side-bulb (plantlet) yearly. It's a big plant. About the time that the
spike first appeared, I had cleaned the gravel in the tank and had
dislodged and cut some of the roots of the plant.
