Salal (Gaultheria shallon) Germination from Seed
I've been seed saving natives!
I've been having trouble finding resources on whether cold/acid/physical scarification is required for the seeds to germinate.
Does anyone here have experience germinating from seed?
One resource (a seed company) says they need floating.

Floating instructions:
"Soak seed 24 hours then surface sow thinly; medium should be an equal mix of sand/peat for the sowing medium. Mist well to create optimum medium-seed contact. Keep moist with via daily misting and use a clear plastic cover to maintain humidity. Needs strong indirect light to germinate (8 hours/day of light is preferred) . Needs warm temps to germinate properly: should germinate within 2-12 weeks at 20 C. "
another (a mostly AI-skimmed blog) says cold scarification for 4-10 weeks

I'll be trying the float method as I want to get them in the ground this year and know summer is not going to be kind to seedlings.
I'll update as soon as I see any sucess.
Hope for some good advice, in the meantime!
