Lilium scale production

Dear all: Please chime in if you grow Lilium en masse or know how cells 

The Laird of Auchgourish wrote that scales of a Lilium bulb can produce new 
small bulbs without a piece of the bulb plate, outside tissue culture / 

I would love to know how that happens. My goal is not to be right from the 
start but to learn.

Might the procedure involve burying the horns of a buffalo when the 
Steinerian moon is blue? Joke.

Iain, you mention "a few wee tricks," and when you are recovered from your 
surgery I hope that you will communicate those tricks to all of us.

Good luck with your operation.
