Advice for fascicularia please

I have had a couple of fascicularia - bicolor and var. canaliculata - for a few years. The bicolor is pretty potbound and neither have flowered, despite having many rosettes. The last one I had flowered wonderfully, and when I tried to split off the young rosettes to keep it going, and it died. So should I take the saw to the bicolor to split it (with associated risk) or just pot it on, and keep waiting?

 

I've never grown it but I know the plant. Pot on every time for me.
In a pot - are you keeping it warm over the winter?

 

It lives outside - had no problem with previous one (the one that flowered) in cold winters. The one that lives in the polytunnel is behaving the same.

 

Have you got a picture?

 

Ok, the F.bicolor var canaliculatus is in the 15 inch glazed pot, the F.bicolor is normally in a 2 litre pot (about 6-8 inches tall pot), and I show its rootball also. And for comparison is a photo of the one that flowered. Looking at it, it looks as though the foliage was broader, so maybe a different variant?

 

I dont half look like What I've got

Scrambling around to find pics.

 

That is DEFINITELY a fascicularia! Just wait till the beautiful little triangular flowers happen!
I am going to try something I just read about epsom salts triggering flowering. Or maybe wrap a ripe banana with it, to produce ethylene...

 

Or an apple.

 

I wondered if you were giving it too much love as the one at OBG blooms year in year out and that is planted out.

@pete don't do little flowers

That's a new one on me! I might try that with Salvia lasiantha.

 

Mine flowered last year, apart from the red bracts I think I missed it

 

@longk - too much love? no chance!
