1 - Overview
‘French Breakfast 4 Francis’ is an unresolved AGM bunching radish with uniform cylindrical roots. Their upper skin is bright red and ends in the characteristic small white tip; inside is tender, crunchy white flesh with a mild peppery flavour.
This cultivar combines high tolerance of summer heat with exceptional speed, maturing in only 21 days under suitable conditions. It is particularly useful for repeated small sowings and for gardeners wanting a reliable warm-season salad radish.
2 - Size
- Ultimate height
- 0.1–0.5 metre
- Ultimate spread
- 0.1–0.5 metre
- Time to maturity
- one year botanically
- Reported edible maturity
- about 21 days
- Root
- uniform, elongated cylindrical red root with a small white tip
- Habit
- clump forming
Thin seedlings to around 3cm apart and harvest promptly while roots are slim, crisp and uniform. Over-mature roots lose the defining tender texture.
3 - Growing conditions
- Suitable soils
- Chalk, clay, loam or sand
- Moisture
- Moist but well drained, or well drained
- Preferred pH
- Acid, neutral or alkaline
Grow in fertile, freely drained soil with enough moisture for uninterrupted growth. Keep plants watered to discourage premature seeding, but do not saturate the ground: excessive water can favour leaves over roots.
4 - Position and hardiness
- Light
- Full sun or partial shade
- Aspect
- South- or west-facing
- Exposure
- Sheltered
- Hardiness
- H2
Use full sun in mild weather and light shade during hot periods. The cultivar's heat tolerance extends the salad-radish season, but regular watering remains essential. H2 plants tolerate low temperatures above freezing.
5 - Colour and seasonal interest
The harvest is visually distinctive: a bunch of evenly sized, slim cylindrical roots with rich red skin over most of their length and a clean, short white lower tip, each ending in a fine taproot. A cut root reveals solid white flesh. Attach compact healthy green radish leaves and exclude round globe roots, purple or black skin and large white daikon proportions.

Genus
Raphanus includes annual, biennial and perennial herbaceous plants, often with lyrate glaucous leaves, small four-petalled flowers and indehiscent fruits. Edible forms are cultivated as annual radish vegetables.
Safety
Roots and young leaves are edible. Wash thoroughly and harvest while sound and crisp.
7 - How to grow
Cultivation
Sow small batches successionally from early spring through late summer. Make shallow drills about 1cm deep, leave 15cm between rows and sow or thin plants to roughly 3cm apart. Maintain even moisture, particularly in summer.
The profile suggests growing alongside mint may help deter pests. Harvest from around 21 days when the cylindrical roots have coloured evenly and remain tender. Do not leave them to become oversized, woody or pithy.
Propagation
Propagate by seed sown directly where the roots will mature.
Suggested locations
- City or courtyard garden
- Cottage or informal garden
- Patio container
- Allotment gap or succession row
Pruning
No pruning is required. Remove premature flower stems from an edible-root crop.
Pests
May be susceptible to flea beetles. Keep seedlings growing strongly and protect vulnerable rows with fine mesh where necessary.
Diseases
The profile records the cultivar as generally disease-free. Avoid overcrowding and rotate brassicas as routine precautions.
