Lovage vs Celery seed
The short answer
Both taste of celery and only one is celery-adjacent by use. Lovage is a large perennial leaf, sweet, slightly aniseed, used by the handful in soups and stocks. Celery seed is a tiny seed of a different plant — smallage — and is intensely concentrated and slightly bitter, used by the pinch. A teaspoon of celery seed in place of a handful of lovage is a common and unrecoverable mistake.
Side by side
| Lovage | Celery seed | |
|---|---|---|
| Botanical identity | Levisticum officinale W.D.J.Koch | Apium graveolens L. |
| Part used | leaf, seed, root, stem | seed |
| Origin | Probably the eastern Mediterranean or western Asia, though the plant has been cultivated in Europe so long that its wild origin is not securely established. | The Mediterranean basin and western Asia, where the wild form grows on damp and brackish ground, with seed production now concentrated in India. |
| Flavour notes | savoury, celery-like, yeasty, green, faintly bitter | earthy, bitter, herbal, warm |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Powerfully savoury with a celery core, a faint bitterness and a lingering depth. It is one of very few herbs that adds what tastes like body rather than aroma, which is why it survives in soup traditions and disappeared from cuisines that stopped making soup. | Intensely celery-like with a pronounced bitterness that the vegetable does not have, and a warm slightly nutty finish. The bitterness is the thing to respect: celery seed is not a concentrated stock cube so much as a concentrated celery leaf, and used at vegetable-like quantities it turns a dish harsh. |
| Aroma | Celery multiplied — intensely savoury, green and slightly musky, with a yeasty depth that is genuinely reminiscent of stock or of a bouillon cube. Rubbing a fresh leaf fills a room. | Immediately and unmistakably celery, and far more concentrated than the vegetable — green, slightly medicinal, with a warm earthiness behind it. A jar opened in a kitchen is recognised instantly by anyone who has eaten celery. |
Can you swap them?
Substitution is directional: the answer is often different in each direction, and both are recorded.
Celery seed
Good matchUse: ~0.25× by volume — A quarter of the volume of dried lovage leaf, and less again against fresh. Celery seed is dense and concentrated where lovage leaf is light.
The closest substitute available in an ordinary shop, and a genuinely good one: celery seed and lovage share the phthalides that give both their savoury depth, so the register transfers almost intact. What changes is the shape of the delivery — a seed extracts more slowly than a leaf and carries a slight bitterness the leaf does not — and celery seed is available everywhere while lovage is not.

Works for
- Soups, stocks and broths
- Anywhere lovage was supplying savoury depth rather than green freshness
Does not work for
- Dishes wanting the fresh green note of the living herb
- Anything already carrying celery or celery seed, which this will double
Which should you buy?
Lovage
The real decision here is fresh against dried, and lovage is one of the few soft green herbs where dried is genuinely worth having: the savoury phthalides survive drying and only the bright green note is lost. If you can grow it, do — one plant supplies a household and returns every year — and if you cannot, a small jar of the dried leaf will do more for a pot of soup than most things on the shelf. Lovage seed is a separate purchase and behaves like celery seed.
Celery seed
Buy whole, and buy a small jar. Whole celery seed keeps for two years or more where ground fades within months, and most of its uses — pickles, brines, dressings, stocks — want it whole anyway. Grind it yourself if a rub calls for it, and use about half what you would use whole, because grinding sharpens the bitterness. Be clear about what you are picking up: celery salt is mostly salt and is a seasoning rather than a spice, and swapping it for celery seed by volume will oversalt whatever it goes into. And check the smell before buying if you can, since spent seed with the oil extracted looks exactly like the real thing.
