Rosa californica

Dear BJ and all,

I've had good results with European Rosa seeds, just by breaking open the 
fruits and sowing the seeds in gritty soil in pots topdressed with gravel, 
in the fall, and leaving them in a cold frame over the winter. They 
usually germinate the following spring. One thing you could try, but I'm 
not convinced it makes any appreciable difference, is to soak the seeds in 
5 per cent hydrochloric acid for several hours, to simulate passage 
through an animal's digestive tract. You can buy the stuff as mortar 
cleaner/remover from a builder's shop (but that may be a 15 per cent 
concentration, so you may have to dilute it).
