Safety Overview
1.Celeriac — At a Glance
Celeriac, scientifically known as Apium graveolens rapaceum, is a distinctive biennial plant cultivated primarily for its edible, swollen hypocotyl, commonly referred to as a root. This unique cultivar of wild celery typically reaches heights of 60 to 90 cm. Its robust foliage consists of deeply lobed leaves, measuring 20 to 30 cm long, displaying a vibrant dark green hue that sets it apart from common celery varieties.
The plant's most striking feature is its tuberous root, which can grow up to 15 cm in diameter, characterized by a knobby, irregular, and rough exterior ranging in color from light brown to pale beige. In its second year, celeriac produces flowering stems topped with small, delicate, white, umbrella-shaped clusters known as umbels, which bloom in late summer and are attractive to pollinators. Native to the Mediterranean basin, Apium graveolens rapaceum thrives in cool, temperate climates and belongs to the Apiaceae family, a botanical group renowned for its aromatic and culinary members such as carrots, parsley, and parsnips.
Its adaptability and unique, earthy flavor profile make it a valued vegetable in both traditional and modern cuisine, increasingly recognized for its nutritional density.
