Allium schubertii
GIANT ORNAMENTAL ONION.
- Unit price
- / per
Allium schubertii, which has various common names including ornamental onion, flowering onion, tumbleweed onion and Persian onion, is a perennial plant that grows from an underground bulb and which produces vivid green, strap-like leaves in the spring, which die back before it blooms. It grows to around 50 cm tall. These flowers consist of 50 or more star-shaped, rose-pink florets on stems of differing lengths producing a starburst effect which can be up to 30-45 cm (12-18") across! The desiccated flower heads eventually break off the dried out, dead stems and, blown around by the desert winds, cast their seeds abroad as they tumble around. The plants live for a number of years, and new plants can be created by saving the seeds from previous years flowers.
Allium schubertii has flower and seed heads that have been compared to fireworks exploding, and both are dried and used in flower arranging, and can even be sprayed with decorative paint and used as Christmas tree decorations. The American Horticultural Society recommends growing these bulbs in AHS planting zones 5-8. It appears, however, that they may be even cold-hardier than that.
Very limited supply.
Type: Hardy perennial
Hardiness zones: 5-8, and likely colder zones as well
Height: 50cm
Location: Sun
Seeds per packet: 3
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.
