Cultural Tips:
Grams per 1000 Seeds: 0,435
Seeds per Gram: 2300
Seeding Recommendation: 1 g / 1000 plants

Germination: JELITTO GOLD NUGGET SEED® germinate after 3 - 4 weeks, keep seed in constant moisture (not wet) with temperatures of about +20°C (68°F). Do not cover the seeds but tightly press into the earth. After germination, the seedlings must be kept cool (+5 to 10°C) (41 to 50°F) in the months with less daylight hours, but must not be exposed to frost. At this time, it is of great benefit if the seedlings can receive at least 12 hours of light per day.

Scheduling:
Best Sowing Dates: Anytime
Sowing to Germination: 3 - 4 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 8 weeks
Cutting-Back at Transplanting: Cut-back once to keep more compact

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: This species is not a suitable candidate for forcing.
Fertilization: Medium (150-200 ppm)
