What Is Celeriac?
Celeriac (Apium graveolens var. rapaceum), also known as celery root, knob celery, or turnip-rooted celery, is a type of celery cultivated primarily for its edible, bulb-like root rather than its stalks. Despite its resemblance to a turnip, celeriac is more closely related to common celery and belongs to the same plant family—Apiaceae. The outer appearance is rough and knobby, but beneath the skin lies crisp, pale flesh with a unique aroma and flavor.
- Pronunciation: suh-LEHR-ee-ack
- Edible Parts: The hypocotyl (swollen root base) is the main edible part; stalks are fibrous and leaves are sometimes used as seasoning.
- Growth: Celeriac is a cool-season crop, maturing over several months in moderate climates.
