Vegetative Erythronium propagation

OK.  Diane here, not just the keyboard acting on its own.  I've taken  
up Paige's challenge and have been tallying my Erythronium oregonum,  
local ones, all seed-grown, and no "White Beauty" has ever been in the  
neighbourhood until this year when I bought one.

I didn't crawl through the bushes, but chose an area that is fairly  
open.  These are all mature plants as every year I remove the seeds  
and send them to various exchanges.  I am counting plants as double  
and triple if they are growing really close together.  This is not a  
guarantee of vegetative increase, of course.

32 single plants.  3 of them have two flowers on the stem, and I will  
mark them.
3 double plants
1 triple
1 group of mostly single leaves with one flower

The triple plants have broad pale leaves that are identical so I am  
sure they represent vegetative increase. I will mark them and  will   
keep the seeds separate and see if they pass on the trait.  There is  
no way I can dig them as they are right up against the trunk of a tree.

Well, thanks for motivating me, Paige.  This is something I have  
intended to do for the past couple of years and hadn't got around to  
it.  Next I should tally my revolutums.  These are the only two  
species I have enough of to bother counting.
