Type: Hardy perennial
Height: 2 feet, 24", 60 cm
Location: Sun or part sun
Hardiness zones: Perennial in zones 4-8
Seeds per pack: 20
Germination: As with many perennial seeds, these seeds benefit from a period of moist cold to help them begin to grow. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds on the surface of your growing medium, and water. Be sure not to bury the seeds as they require light to germinate. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks (light is not required at this point). Once the cold period is completed, place the container in a bright room, at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
