For zones 3-10.  Easiest way to sow these is to put them out in fall after your first hard freeze.  Mix your seed packet with 4 cups of screened peat and lightly spread.

You can also start early in pots, or direct sow in spring.  Rudbeckia do not have to be cold treated, but a quick cold treatment will increase your germination rate.  If cold treating first mix your seeds with teaspoon of fine sand or fine peat and add 1 teaspoon of water so your mixture is moist but not soggy.  Place in your refrigerator (not freezer) for 30 days.  Let your mix dry out on the counter in late winter sow into pots and transplant after your last frost in the spring.  These need light to germinate so when sowing into pots sow seeds on the surface of your potting mixture and lightly dust with fine sand or vermiculite.

After the cold treatment you can also direct sow these into your garden in the spring after your last frost.  Mix your cold treated seeds with 1/4 cup of screened peat or sand and use the shaker method to distribute them into your garden area.  Once you seedlings are 2" tall you can transplant to 12" spacing.
