The Elegant Frost, The Radish of Refined Geometry and Subtle Northern Beauty

White Icicle is the radish that looks like winter translated into spring.

Long and slender, pristinely white, it rises from cool soil like a small piece of frost. It has clean lines, quiet beauty, and a crispness that feels almost architectural. Slice it, and you get a refined snap and a gentle peppery brightness. It is less fiery than some red radishes, but still unmistakably radish: fresh, sharp-edged, and alive. This is the radish for gardeners who love contrast and a pale, elegant root that makes the harvest bowl look curated.

A whisper of history

Radishes have been cultivated for thousands of years, but White Icicle reflects a European tradition of selecting vegetables not only for speed and flavour, but for shape and presentation. Long, tapered radishes became a beloved counterpoint to round spring types, a different geometry for the same early-season joy.

What You’ll Grow

• Plant type: Cool-season annual root crop
• Growth habit: upright leaf rosette
• Root size: typically 510 cm (34 in) long and 1.251.9 cm (0.50.75 in) wide
• Shape: long, slender, tapered
• Skin colour: pristine white
• Flesh: crisp, white, fine-grained
• Flavour: mildly peppery, clean, refreshing

Days to maturity: typically 25 to 30 days (best quality in cool weather).

Growing Instructions

White Icicle is at its best when it grows steadily in cool weather. Give it loose soil for straight roots, consistent moisture for tenderness, and harvest on time for peak crispness.

When to Plant

• Sow as soon as the soil can be worked in spring
• Sow again in late summer for a fall crop when nights cool

Direct Sowing (Best Method)

• Sow seeds 5 cm (1/2 in) deep
• Space seeds 55 cm (12 in) apart
• Rows 1530 cm (612 in) apart
• Thin promptly to 55 cm (12 in) spacing for straight, well-formed roots

Succession Planting

• Re-sow every 10 to 14 days through spring
• Pause during hot weather (heat can increase pithiness and bite)

Site + Soil (Key for Long Roots)

• Full sun to part shade (6+ hours)
• Loose, well-drained soil is essential (stones/compaction cause bending and forking)
• Work in compost before sowing if the soil is poor

Watering

• Keep soil evenly moist:
• Dry spells can cause tough roots
• Light mulch helps keep soil cool and moisture steady

Feeding

• Light feeder
• Avoid excess nitrogen (lush tops, smaller roots)

Pest Notes

• Watch for flea beetles and root maggots
• Row cover early can help; keep beds weed-free

Harvesting (For Peak Tenderness)

• Harvest at 5 to 10 cm (3 to 4 in) long (or to preference)
• Pull gently when roots are visible at the soil line
• White Icicle can be harvested a little larger than globe types, but don’t leave it too long if you want the most delicate crunch

Preserving + Storage

• Remove greens before storing
• Refrigerate in a bag/container with a little humidity
• Often keeps up to 2 to 3 weeks when fresh and properly stored

Quick preserves: – Refrigerator pickles (vinegar, salt, sugar, spices) – Fermentation for tangy crunch

Culinary Notes: Crisp, Clean, Elegant

White Icicle shines anywhere you want crispness without overwhelming heat.

• Salads: thin half-moons or matchsticks for clean crunch
• Crudites: whole or halved for sculptural presentation
• Butter + salt: a softer, gentler version of the classic radish ritual
• Pickling: keeps the snap and turns the flavour bright
• Roasting: mellows the bite and brings out the sweetness
• Greens: saute9, stir into soups, or blend into pesto

Canadian Climate Notes + Growing Zones

White Icicle is a natural fit for Canadian springs and cool shoulder seasons.

• Sow early for the crispest, mildest roots
• In warm spells, keep moisture steady and offer afternoon shade
• Sow again in late summer for a fall harvest

Growing zones: 2 to 10 (annual; cool-season crop).

Seed Saving

Radishes are biennial for seed: they must bolt and flower.

Isolation & Cross-Pollination

Radishes cross with other radish varieties.

• For purity, isolate by 800 m (1/2 mile) or grow only one flowering radish variety

How to Save Seed

1. Choose a few of the best roots and leave them in the ground (or replant) to bolt
2. Let plants flower and form pods
3. Harvest pods when they turn brown and dry
4. Dry thoroughly, then thresh pods to release the seed
5. Store cool and dry

Seed viability: typically 4  to 5 years.

White Icicle is refined geometry in edible form, a pale, crisp radish that makes spring feel clean, bright, and quietly beautiful.
