- / per
Very large flowering. Moderate self-sowing at suitable locations. A North America native with large saucer-shaped pure white flowers and bluish green foliage. Drought tolerant and suitable for natural landscaping. Use for low maintenance plantings. Easy to grow.
Type: Hardy perennial
Hardiness zones: 3-11
Height: 100cm, 39"
Location: Sun
Seeds per packet: 10
Sow just under the surface of the soil and water in. Leave them at room temperature for 6 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 80 days. 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 for most seeds, though some can take longer.
Ornamental use only. These seeds and/or plants are poisonous.
