In the BACPS Newsletter fall '98 issue there was a reprint of an article by
Aaron Ellison on the effects of various seed treatments on Sarr. seed
germination. The optimum fro S. leucophylla was 4 weeks of cold, moist
stratification ( at 4 deg. C. or about 39 deg F. ).
I have used a mix of washed white silica sand and a bit of moist milled
sphagnum for the medium of stratification, and my less than perfectly
temperature-controlled refrigerator to chill the seed. I label the jar with
the date to remove the seed ( this might also prevent spousal termination of
the stratification ). This has been very successful, although it would appear
S. leucophylla has a lower overall germination rate than most other Sarrs.
Hope this helps
