- Unit price
- / per
Allium unifolium goes by common names American Garlic, or One-Leaved Onion. Despite its name, it usually has 2-3 flat leaves up to 50 cm long. It is a North American species of wild onion. It is native to the coastal mountain ranges of California, Oregon, and Baja California, and is grown in other areas of North America and hardy in zones 5 and up.
The plants form bulbs that are egg-shaped, up to 2 cm long, often formed at the end of rhizomes spreading out from the parent plant. The flowers grow up to 30-80 cm tall, and up to 15 mm across, and are usually pink but occasionally white, with anthers yellow or purple.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Height: 30-80cm, 12-30"
Location: Sun
Hardiness zones: 5-10
Seeds per packet: 10
Availability: If these seeds are showing out of stock, we strongly recommend joining our wait list, as these seeds have a very shorty viability window, and this helps ensure you get the freshest seeds possible! If they are available, they will only be available for a limited time.
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.
Ornamental use only. These seeds and/or plants may be poisonous.
