Canarina Seeds

Seems a bit extreme. A tried-and-true method for many seeds that come from
fleshy fruit is fermentation. It can also speed germination afterward. All
I do is put the seeds (and a bit of the fruit and its juice) into a small
glass and add water so they are covered by half an inch or so. Then I let
it sit for a few days while the liquid ferments. After it gets bubbly and
possibly even grows a bit of mold on the surface of the liquid, you can
clean it with clear water. If the seeds still has flesh adhering, it's easy
to rub it off with a bit more water.

You can also substitute a bit of fruit juice for the water to speed it
along if there is too little juice in the original fruit. I'm guessing the
biochemical activity is similar to what happens when the fruit is eaten and
passes through a bird's gut (fruit eater, not a seed eater whose gizzard
would grind them up!)

Sometimes I give a final bath in household strength hydrogen peroxide. This
has worked for seeds that need cleaning, and for some seeds that are slow
to germinate without the 'bird gut' treatment. I've also dried and stored
the seed afterward, and they germinate just fine some time later.

Here's a more "official" description of the technique:
