Answer: Stephen joined in November 2011, so he doesn't have to renew 
until January 2013. People who join after October 1 are considered to 
be paid through the following calendar year, but thereafter they need 
to renew each January. For example, someone who joined in July 2011 
needed to renew in January 2012. This policy has to do with the 
mailing schedule of the print newsletter, which is the largest 
ongoing expense paid for by dues.

I haven't succeeded in flowering Lilium bolanderi, which is 
notoriously difficult outside its native range, but I have raised 
plants that lasted about 4 years. My advice is not to disturb the 
seedling bulbs for two years, and when you do move them on, take the 
whole ball of soil from the seed pot with as little disturbance as 
possible and put it right into a larger pot, unless you have a large 
number of small bulbs.

Note that plants often seen on serpentine (ultramafic rocks and their 
soils) do not require this type of soil; they are tolerant of it and 
are thought by some botanists to grow there by preference because 
many other plants can't tolerate the high level of magnesium, so 
there is less competition. Another theory is that the unusual mineral 
composition helps the plants resist disease. I don't know if either 
of these theories has been scientifically tested. Serpentine is 
common in the Siskiyou Mountains of southern Oregon.
