A traditional method for canna seeds and others with really hard seed
coats is to either chip off a piece of the seed coat or to sandpaper
the seed coat thin in one spot. Water can get in through the small spot
and the seed will germinate.
Many hard coated seeds are eaten by birds in nature and passed out with the
feces after the gravel-filled gizzard has worked them over.
