I have no idea. Why do the French call potatoes "Pommes de terre?" ("Ground Apples")
Anyway, here's a brief wiki article:
https://en.wikipedia.org/wiki/Elephant_garlic
"
Elephant garlic (
Allium ampeloprasum var.
ampeloprasum) is a perennial plant belonging to the
onion genus. It is not a true
garlic, but actually a variant of the garden
leek. It has a tall, solid, flowering stalk and broad, flat
leaves much like those of the leek, but forms a bulb consisting of very large, garlic-like cloves. The flavor of these, while not exactly like garlic, is much more similar to garlic than to leeks. The flavor is milder than garlic, and much more palatable to some people than garlic when used raw as in salads. It is sometimes confused with
solo garlic."
