Allium sphaerocephalon
ORNAMENTAL ONION
- Unit price
- / per
A unique summer-flowering ornamental onion that has straight stems, topped with egg-shaped flower heads. They start off completely chartreuse-green before turning maroon-claret at the tip and finally becoming overall deep reddish purple. Flowering lasts for many weeks.
Type: Hardy perennial
Hardiness zones: 4-11
Height: 60-90cm, 2-3'
Location: Sun
Seeds per packet: 10
Surface sow as light aids germination. Water the seeds in. Leave them at room temperature for 5 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 (15C, 59F) for them to germinate. Germination is generally 30-90 days after the warming period, though some can take longer.
