Elephant Garlic, like all hardneck garlic types, produces a flowering spike or flowerhead known as a “scape". These eventually, by July, become 6ft high purple flowering balls like other flowering alliums in the garden. However, most growers snap the scape off as it appears, to encourage enlargement of the bulb.
The scapes have a mild garlic/allium flavour and are delicious - blanched / sauted or barbecue-d.
