🥔 Brilliant Celeriac
What it looks like
Why this variety
Brilliant is the modern, polished celeriac: a Dutch variety listed at 110 days, producing large, round, crisp white roots with few external markings and a nutty flavor with mild celery and parsley notes, according to West Coast Seeds. Where Giant Prague is knobbly and characterful, Brilliant is smooth and vigorous — the root that looks like the picture.
Smooth matters in the kitchen: less trimming, less waste, and a root that peels cleanly into even pieces for soup, mash, or raw rémoulade. Brilliant is also noted as easy to grow and harvest, which is not a phrase you hear often about celeriac.
If you are new to choosing between cultivars, the Varieties Matter guide explains why the name after the plant matters as much as the plant itself. And if you want the whole clan at a glance, the broader Celeriac guide covers celeriac generally.
How to grow
In Florida, celeriac is a winter project: start seed indoors in late summer, transplant into the cooling fall, and harvest knobbly roots through winter. It needs a long, steady season, so do not rush it — the root swells late, and patience is the fertilizer here.
Start indoors 10–12 weeks ahead, transplant into rich, moist soil, and keep the water absolutely steady. Celeriac’s long season means a long time to go wrong, and the way it goes wrong is almost always drought — mulch deeply and water on schedule.
Water & feeding
Celeriac is a celery cousin and drinks like one: consistent moisture, no drying out, mulch to hold it. Feed with compost and a balanced fertilizer through the season, and trim the side roots late in the season to push energy into one smooth, round root.
Common problems
Celery leaf miner, aphids, and slugs are the usual pests; none are usually fatal. Root splitting and woodiness come from uneven water, and a plant that bolts after a cold snap in spring will not make a good root — transplant after the weather has settled.
Harvest
Lift when the roots are large and the tops yellow, after a light frost if you can. Trim, store cool and humid, and use through winter — Brilliant stores well, like its heirloom cousin.
Nerdy fact: Brilliant’s smoothness is a breeding achievement, not a cosmetic one: fewer side roots means the plant puts its energy into one clean root instead of a tangle of small ones — which is why it peels like a dream.
Saving seeds
Brilliant is a modern Dutch variety, so it comes true from seed — save seed from your best plants and let them dry fully before storing. The full method is in the Saving seeds section of the Celeriac guide.
