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

Germination to Transplant: 4 - 8 weeks
Transplanting to Potting: 6 - 10 weeks
Cutting back at Transplanting: Cut-back once to keep more compact.
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2") / 2-3 plugs per 15 cm (6")
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: This species is not a suitable candidate for forcing.
Fertilizer: Medium (150-200 ppm)
