How to Grow
1,800 seeds/gram. Start seed indoors in early March in a soil-less mix. Press the seed into contact and no deeper than 3 mm (1/8″) with the soil-less mix but do not cover as light aids germination. Place the seed in a refrigerator for a 30 days cold treatment before bringing the container back to the warmth. Germinate at 21 C (70 F) then grow on under lights at a slightly cooler temperature. Harden off then transplant outside to a sunny spot after the danger of frost has passed. Seed can also be directly sown outdoors in the fall for natural stratification.
