Culture: Likes cool moist conditions. Very slow to give in to fall frosts. May be direct seeded in early spring or started indoors and grown on at 55° and set out in 8 weeks. Does not germinate well in warmer temperatures. Refrigerating for a week improves germination. Cut when one third of the flowers on the stem are open. For cuts, vase life is 6–8 days. Excellent for drying. ~330 seeds/g. except for Blue Cloud.
All flowers are annuals except where noted. All flowers are open-pollinated except where noted.
Days in parentheses after a variety indicate days to first bloom.
