Cultural Tips:
Grams per 1000 Seeds: 0,120
Seeds per Gram: 8300
Seeding Recommendation: 0,5 g / 1000 plants
Sowing Rate: 4 seeds per cell
Plug tray recommended size(s): 128, 288
Germination: These seeds germinate rapidly depending on species and origin. If germination does not occur after 3-4 weeks a cooling period of 2-4 weeks is recommended.

Scheduling:
Best Sowing Dates: November - March
Sowing to Germination: 8 - 12 weeks
Germination to Transplant: 4 - 6 weeks
Transplanting to Salable Plant: 4 - 6 weeks
Cutting-Back at Transplanting: Not necessary

Growing On:
Container Size(s): 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: Medium (150-200 ppm)
