Lilium bolanderi germination

Oakland is at one end of a bridge across from San Francisco.  It is  
also a coastal city.

I have not tried bolanderi, but this year I am buying some.

I have grown other North American species and treat them as I treat  
all large seeds:  sow them in damp seedless mix in a small ziplock  
bag. Then I put them in a biscuit tin in a cool spot, like my  
unheated bedroom or a frost-free greenhouse.  (as opposed to things  
like trumpets which I leave lying around in the light on a kitchen  
counter.)

I count them as "germinated" if there has been some activity, like an  
emerged radicle or a teeny bulb.

I have had "American hybrids" germinate in one month (from March to  
April.)

With wild-collected species, I have had these times:
columbianum - 5 months from January
kelleyanum and kelloggii - 2 months from April
vollmeri - 5 or 6 months from March
washingtonianum - 11 months from January

So they vary quite a bit.
