Hydrastis canadensis
GOLDENSEAL
- Unit price
- / per
Type: Hardy perennial
Hardiness zones: 3-8
Height: 15", 38cm
Location: Shade to part shade
Seeds per packet: 5
Sow just under the surface of the soil and water in. First keep them at room temperature for 8 weeks. This helps break the phytohormones which inhibit germination. Then cover them with plastic to retain moisture, and then place in a fridge for 8 weeks. Then bring them to a cool room (approximately 12°C, 54°F) for 8 weeks for germination. They may be growing at this point, though often they need a second cold period. If they are not growing cover them with plastic and place in a fridge for another 6-8 weeks. Be sure they stay moist. After the second cold stratification period they are then brought back to a cool (12-15°C, 54-59°F) room for them to germinate. This double cold period is not always needed, but sometimes necessary, and is very normal for these seeds. Germination is in 4-12 weeks after the second warming period.
Ornamental use only. These seeds and/or plants are poisonous.
