Well be careful how many you sow!! I sowed heauchera seed one year in a flat, must have been 300 in there by the time germination was finished. All my friends have some, sent some to members on here and planted so many on a hillside I was planting. Still had those things in pots!!! Good luck! I wonder if they need a bit of cold stratification before planting. You might want to research where they come from and try to mimic mother nature. Just a thought.
