Celeriac
Aromatically bold from the first peel—Celeriac forms a knobby, turnip-like root with a clean, celery-bright fragrance and a pleasantly nutty, mellow bite.
Its flesh turns tender and creamy when cooked, with a fine-grained texture that holds its shape beautifully for hearty roasts and velvety purées. Grow for the distinctive, herb-like character that makes this market-class favorite a standout in winter storage and savory preparations.

Wait until soil reaches 45°F and nights stay above 28°F before moving outdoors. Harden off for 5 days first.
Expert Note
For the best knob size, keep moisture even and avoid burying the crown—hilling dirt too high can reduce root-forming quality.
