Allium sphaerocephalon, commonly known as the round-headed leek or drumstick allium, is a bulbous perennial plant in the Amaryllidaceae family. Native to Europe, it is known for its striking, spherical flower heads that bloom in shades of purple and green. This plant is well-suited to temperate climates and typically enters a dormancy period during the winter months.
