Germination: The sowing must be kept warm (about +18 to 22°C) [about 64 to 72°F] and moist for the first 2-4 weeks. After this period the sowing must be kept at a cold temperature (between -4 and +4°C) [between 25 and 39°F] for another 4-6 weeks. It is not so important if the temperature is higher or lower during the cooling period, but the cooling period has to be prolonged because the synthesis of the germination inducer, hormonlike acid, slows down or comes to a standstill. It is beneficial to cover the sowing with snow during the cooling-period. The temperature below it usually keeps in the optimum range of -4 to 0°C [25 to 32°F]. The sowing is kept moist, and the melting snow helps to destroy the shell, which is advantageous for the germinating seedling. After this cooling-period the sowing may not be immediately exposed to high temperatures. The most effective temperatures are between +5 to 12°C [41 to 54°F], even if germination has started. The best location for this sowing, even in March, April and May, is the open field, the cold frame or a cold greenhouse.

The directions above do not always show the best results. After the cooling-period some species need a longer time until germination starts. As some seeds do not germinate until the next year, it is important not to throw away the seed boxes too early.

Scheduling:
Best Sowing Dates: November - March
Sowing to Germination: 10 weeks or longer
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 10 weeks
Cutting-Back at Transplanting: Not necessary

Growing On:
Container Size(s): 1 plug per 8/9 cm (3 1/2''); 1-2 plugs per 11/12 cm (4 1/2'')
Vernalization: There is no current research on vernalization but a prudent recommendation for any perennial would be 6-12 weeks (a few might need 15 weeks!) at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality.
Forcing: An obvious place to experiment - following vernalization - would be raising daytime temperatures to 60° - 65°F (15° - 17°C). Provide 16 hours of continuous lighting. During the short days of winter, provide a night interruption lighting of 4 hours between 10:00 p.m. and 2:00 a.m.
Fertilization: Light (100-150 ppm)
