Allium zebdanense is an ornamental onion found throughout the Middle East including Israel, Syria, Palestine, Lebanon, Turkey and Jordan, extending as well into the Caucasus. It has Carex-like foliage that forms an arching mound and flower stems that reach 45 centimetres. The somewhat nodding flowers are pristine white, in a semi-rounded umbel. It was first described in 1859 by Pierre Edmond Boissier and Friedrich Wilhelm Noe.
From April in the south to June in the north.
This Allium does well in dry shade but will also do well in full sun. It is not fussy about soil pH doing fine in both mildly acidic and alkaline soils, but the soil must be well-drained. Plants will go dormant by early to mid-summer so interplant so you are not left with a gap. Despite being native to rather mild regions, it is hardy to at least zone 5.
Bulbs should be planted about 7-10 cm, deep, in groups of 7 or more for the best impact.
