Elephant Garlic bulbils?

    Elephant garlic - left to grow wild. They spread from the cloves at the base of the stem.

    Elephant garlic - has been harvested and replanted. Your cloves, JJB/SC were dug up here.

    Babington Leeks left to grow wild. They "self seed" by dropping the bulbils that form in the flower head. The Bulbils I shared came from these plants. 

. Photos taken today. Both sorts (EG & BL) look very similar - but the flower heads are different.
