Type: Hardy perennial

Hardiness zones: 3-8

Height: 12", 30 cm

Location: Part shade, part sun

Seeds per pack: 5

Germination: Start these seeds right away to preserve viability, no matter the time of year. Sow the seeds just under the surface of a sterile seed-start mix, and water in. Then cover them with plastic and place in a fridge for 5-6 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to room temperature (20-22 °C, 68-72 °F) for them to germinate. Germination is generally within 60 days after the warming period, though they could take a few months. If possible, the best location for sowing in March, April and early May, is in a cold frame or cold greenhouse where they will receive the cold period and fluctuating temperatures naturally.
