Grams per 1000 seeds: 1,563
Seeds per Gram: 1,0 g = 640. 
Seeding Recommendation: 5 g /1000 plants.
Sowing Rate: 3-4 seeds per cell.
Germination: the sowing must be kept warm (about +18 to +22°C) 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) 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. 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, 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.
Best Sowing Dates: November - March.
Sowing to Germination: 8-10 weeks.
Germination to Transplant: 4-6 weeks.
Transplanting to Salable Plant: 6-8 weeks Cutting-Back at.
Transplanting: not necessary.
Vernalization: a prudent recommendation would be to provide 6-12 weeks at an average daily temperature of +5°C. Exposure to cold may not be necessary for flowering but might improve quality.
Forcing: this species is not a suitable candidate for forcing.
