Not a Lily.

“Marriage? It’s like asparagus eaten with vinaigrette or hollandaise, a matter of taste but of no importance.”
Françoise Sagan

Asparagus was once classified in the lily family, like the related Allium species, onions and garlic. However, genetic research places lilies, Allium, and asparagus in three separate families — the Liliaceae, Amaryllidaceae, and Asparagaceae, respectively — with the Amaryllidaceae and Asparagaceae being grouped together in the order Asparagales.

So asparagus is not a lily.
