Height: 90cm, 36"
Hardiness zones: 5-9
Location: Sun or shade
Seeds per packet: 10
Sow just under the surface of the soil and water in. Leave them at room temperature for 4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 6 weeks. Be sure they stay moist. After the cold stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period, though some can take longer.
Ornamental use only. These seeds and/or plants may be poisonous.
