Plug tray recommended size(s): 72 / 128
Sowing Direction:

(16) See 15 with the exception of germination being slower and more irregular. This poses no problems.

(15) Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Do not cover very small seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.

Best Sowing Date
(northern Hemisphere, Field condition):
Anytime
Sowing to Germination: 2 - 3 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Potting: 6 - 10 weeks
Cutting back at Transplanting: Not Necessary.
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.
Fertilizer: Light (100-150 ppm)
