For zones 3-10 these Cardinal flowers are easy to sow. You can direct sow them in early winter. The seeds are very small and the best way to distribute them is to mix with sand or screen peat and distribute over your prepared garden bed.
You can also start early in pots, or direct sow in spring, but they will need to be cold treated first. Mix your seeds with 1/8 cup of 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 600 days. Let your mix dry out on the counter in late winter and 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 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 as these seeds are very small. Once you seedlings are 2" tall you can transplant to 12" spacing.
