Tips & Reviews

'Rose de Berne' Beefsteak Tomato – historic rarity with an intense, aromatic flavor. 

This variety is a pink beef tomato with an exceptional, intensely aromatic flavor and fruity sweetness. It ripens mid-late and is ideally suited for cultivation in greenhouses, protected outdoor beds, and large containers. Robust, high-yielding, and perfect for self-sufficiency as well as organic growing.

 

  Origin & History

'Rose de Berne' is an open-pollinated beef tomato and ranks among the oldest known Swiss tomato varieties. Preserved to this day by seed savers and home gardens, it appears in old Swiss seed catalogs from the 1940s, sometimes also under the French name Rose de Berne. Originating in Switzerland, it is now considered one of the classic heirloom varieties.

Especially in French-speaking Switzerland and in France, it spread early on, which explains its international diversity of names. Later it also became known as the Bernese Rose Tomato and today belongs to the most popular historic varieties in collections and home gardens worldwide. Its fine balance of sweetness and acidity makes it a true delicacy and a symbol of the richness of traditional tomato culture.

 

  Appearance & Characteristics

The plant grows indeterminately as a stake tomato and reaches a height of about 200–250 cm. It develops strong fruit clusters and bears robust, dark green foliage.

Fruit details:

  • Size: Medium to large, approx. 200-400 g per fruit (sometimes variable)

  • Shape: Flattened-round, slightly ribbed

  • Color: Evenly pink, often with a delicate sheen

  • Texture: Juicy, tender flesh with a thin, soft skin

  • Flavor: Intensely aromatic, fruity and sweet – a true delicacy

 

 Usage & Cultivation Highlights

'Rose de Berne' fruits are excellent for fresh salads, decorative tomato slices, flavorful snacks, as well as soups and sauces. With their pink coloration and intense aroma, they are a true eye-catcher on the plate.

Thanks to their robustness, the variety thrives reliably in protected outdoor beds, greenhouses, and large containers. It impresses with a long harvest period and stable fruit set well into autumn, delighting with particularly aromatic fruits, vigorous growth, and open-pollinated quality – a true highlight for organic cultivation and self-sufficiency.

Compared to other beef tomatoes, 'Rose de Berne' stands out with its particularly intense flavor and versatile use – a robust, open-pollinated variety with exceptional character that enriches every collection garden.

Cultivation guide for

<tc>Rose de Berne</tc>

Growing difficulty:

Medium
In subtropical climates, pre-cultivation is possible from January - transplant outdoors from March in full sun, once day and night temperatures remain consistently above 15 °C.
In temperate regions, start indoors from March – transplant outdoors in full sun from mid-May after the last frost.
Sow in deep, well-drained, humus-rich and nutrient-rich loamy soil - 0.5-1 cm deep. Plant spacing: 50 × 70 cm.

Special features:

High-yielding, Sun-loving / sunny, Resilient, Heat-tolerant

Cultivation tips:

Beefsteak tomatoes are typically grown with a single stem to promote better air circulation and fruit development.
In temperate climates, a rain cover is recommended – a simple roof or plastic tunnel is sufficient.
A sturdy support structure with tomato hooks provides secure hold for the stems, boosts yield, and makes plant care easier.
When transplanting seedlings, plant them deep into the soil up to the base of the seed leaves – this encourages strong root development and supports healthy growth.
Consistent watering enhances fruit quality and promotes healthy plant growth.
At temperatures below 5 °C, plant growth slows significantly - cold stress can hinder development.
Regular harvesting encourages new fruit set and increases overall yield.
Biochar and rock dust improve soil structure and enhance the retention of nutrients and water.

Storage instructions:

Store seeds in a cool, dry, dark, and airtight environment to maximize shelf life and germination.

Propagation:

This tomato variety is self-pollinating but can also cross-pollinate via insects. It belongs to the species Solanum lycopersicum and produces bisexual flowers.
To ensure pure seed collection, it is recommended to maintain a minimum distance of 10–20 meters or more from other tomato varieties, as insect pollination can lead to unintended cross-pollination.
This tomato plant is perennial and forms clusters of flowers after blooming, which turn into fruit packed with seeds.
Tomato seeds are ready for harvest when the fruits are fully ripe and slightly soft to the touch.

Sowing & Planting

Germination

Planting

Germination type:

Repeated cultivation at the same site increases disease pressure, leads to nutrient depletion, and impairs soil structure.
Ideal previous crops include legumes, onions, root vegetables, and green manure – rotating crops supports healthy soil.
Crop rotation with low-nutrient-demanding plants is recommended to prevent soil fatigue and maintain healthy growing conditions.
Plan a green manure crop between heavy-feeding plants and this tomato variety to restore soil fertility.
