Given at the end of each description to give you specific information.
(1) Germination occurs between 70-85°F and within 6-15 days. Sow indoors and cover lightly.
(2) Needs a period of pre-chilling. Mix seeds with moistened peat moss and place in plastic bag. Seal and place bag in an area where the temperature is around 60°F for 2-3 days. Then place in the refrigerator for 30-90 days. After pre-chilling, place seed on sterile seedling mix and cover lightly. Germination may take up to 30 days.
(3) Needs darkness to germinate. Remove cover as soon as germination occurs.
(4) Direct sow in the garden as soon as the soil warms to at least 55°F.
(5) Germination may be slow and erratic. A fluctuating temperature of 75°F during the day and 50°F at night may help.
(6) Needs at least 12 hours of light per day to germinate. Press into the medium but do not cover. Keep moist.
Note: For those varieties that indicate a (1) or (6), a very light covering of vermiculite will allow adequate light to the seed and keep it uniformly moist.
• To promote deep roots and strong stems, water deeply but infrequently
• One to two cups of TSC’s Complete fertilizer per 10 row feet in the spring is adequate for the year
• Germination code: (4)
Insects & Diseases

Annual. All varieties open-pollinated unless otherwise indicated. All varieties have pollen unless otherwise noted.
Culture: Easy to grow. Start indoors 3–4 weeks before last frost at temperatures of 65–75° or direct sow after frost, 3 to a pocket. Thin to best plant, 1′ or more apart. Rich friable soil yields tallest plants; drought stunts growth. Will readily self-sow; for some fun leave a few volunteers in strategic locations.
All flowers are open-pollinated except where noted.

Direct Seed (recommended): After frost, sow 2 seeds every 18-24” & thin to one. More fertility, space & sun = larger plants & flowers. Harvest blooms for continued flowering.
Transplant: Sow indoors 2 weeks before & transplant after last frost at spacing below, disturbing roots minimally. More fertility, space & sun = larger plants & more flowers.
