Cultivation & Characteristics

Tips & Reviews

'Blanche Ronde a Œuf' Eggplant – dwarf landrace with white, egg-shaped fruits. 

This compact, early-ripening eggplant produces exceptionally white, egg-shaped fruits with a mild, nutty, aromatic flavor. With its low growth habit, it is perfectly suited for cultivation in greenhouses, protected outdoor beds, and especially in pots. Robust, productive, and open-pollinated – an ideal variety for self-sufficiency and organic gardening.

 

  Origin & History

‘Blanche Ronde à Œuf’ is an open-pollinated eggplant from France and a historic landrace with a long tradition in French vegetable cultivation. The name means “White Round to Egg” and refers to the characteristic egg-shaped form and the white color of the fruits, reminiscent of chicken eggs. Cultivated in home gardens for many generations, it was especially widespread in rural regions. As early as the 19th century, it appeared in garden catalogues as a “curiosité potagère” (vegetable curiosity). Its unusually white fruits made it not only a culinary specialty but also a popular ornamental plant in cottage gardens.

During the 20th century, the variety largely fell into obscurity due to industrialization and the increasing spread of modern hybrid varieties. Today, it is once again cultivated by organic seed initiatives and conservation organizations and offered as a historic rarity. Characteristic are its strikingly white skin and creamy flesh – a rare feature at the time, which quickly made it a horticultural highlight in the vegetable garden and a valuable contribution to biodiversity.

 

  Appearance & Characteristics

The plant grows compact and upright, reaching a height of about 40 cm. It produces numerous fruit clusters and bears strong, dark green foliage with characteristic violet leaf veins.

Fruit details:

  • Size: Small to medium, approx. 40-60 g per fruit

  • Shape: Egg-shaped to round, approx. 5-7 cm long

  • Color: Pure white with creamy flesh

  • Texture: Tender, juicy, few seeds

  • Flavor: Mild-nutty and aromatic - versatile in use

 

 Usage & Cultivation Highlights

The fruits are excellent for fresh consumption, cooking, frying, grilling, and especially stuffing. Their mild, nutty flavor and striking white color make them a true eye-catcher in vegetable dishes, adding a unique visual and culinary touch.

Thanks to its compact growth and resilience, the variety thrives reliably in greenhouses, protected outdoor beds, and especially in pots. It ripens early, produces abundant fruits, and impresses with its versatility. In addition, it is easy to care for, adapts well to different locations, and delivers stable yields even in changeable weather. Its decorative white fruits ripen evenly, making the plant not only a culinary but also a visual highlight in the garden.

Compared to other eggplants, ‘Blanche Ronde à Œuf’ is very compact, particularly mild, and highly ornamental – ideal for those seeking open-pollinated eggplants with exceptional appearance and history.

Cultivation guide for

<tc>Blanche Ronde a Œuf</tc>

Growing difficulty:

Easy
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, Low-maintenance, Resilient, Heat-tolerant

Cultivation tips:

Eggplants are heat-loving and thrive only at temperatures above 20 °C.
At temperatures below 15 °C, plant growth slows significantly - cold stress can inhibit development.
In temperate climates, a rain cover is recommended – a simple roof or plastic tunnel is sufficient.
Bring pots indoors or into the greenhouse in autumn – this way the season can be significantly extended.
Consistent watering enhances fruit quality and promotes healthy plant growth.
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 method:

Generative propagation by seed

Propagation:

This variety belongs to the species Solanum melongena and is predominantly self-pollinating.
For seed production, a minimum distance of 50–100 m from other varieties of the same species is recommended to prevent cross-pollination.
The plant is perennial - after flowering, the typical fruits develop, which at full maturity contain numerous seeds.
Seeds are ready for harvest once the fruits are fully matured, change color, and the flesh begins to dry out.

Sowing & Planting

Germination

Planting

Germination type:

Pot culture:

Requires a minimum container size of 15-20 liters.

Sowing depth:

0,5-1 cm

Plant spacing:

50 cm

Germination temperature:

25-28 °C

Row spacing:

70 cm

Germination time:

6-14 days

Not suitable for baby-leaf cultivation.

Pricking out / thinning out:

3-4 weeks, thin out after formation of the first true leaf pairs.

Planting time:

Crop rotation guidelines:

Do not plant after other nightshades – a minimum crop rotation interval of 3 years is recommended.
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.
Avoid planting directly after heavy-feeding crops – allow the soil to recover and replenish nutrients first.
