This tall leek has spread all over Guernsey and is easily seen in tall clumps on the roadside grassy foreshores of the island. At first the flower head is covered by a paper like sheath which hangs down on the right in the photo. Allium ampeloprasum occurs in Cornwall in reasonable numbers and the Channel Islands but is rare elsewhere according to Stace. var bulbiferum has bulbils and flowers in a compact head.

Although the botanist Babington called it "my leek" this one is var. bulbiferum not var. babingtonii. The bulbils can't be seen here.
