About
Allium schubertii, which has various common names including ornamental onion, flowering onion, tumbleweed onion and Persian onion, is a species of monocotyledonous flowering plant. It belongs to the onion and garlic genus, in the subfamily Allioideae of the family Amaryllidaceae. It occurs in the Levant and Libya.
How to grow it
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. This depends on the heaviness of the soil: in heavier soil that retains water in winter, the survival of these plant is significantly decreased.
Where it grows
Allium schubertii is found in Israel, Palestine, Syria, Lebanon, Turkey and Libya but grown as an ornamental elsewhere.
