Delicate and attractive kohlrabi

The Brassica oleracea Ametyst F1, better known as Ametyst F1 kohlrabi, is an early-maturing hybrid variety distinguished by its uniform, flattened tubers and beautiful blue color. This kohlrabi is both aesthetically pleasing and culinary versatile. Thanks to its delicate texture and attractive shape, Ametyst F1 is a jewel not only in the vegetable garden but also in the kitchen.

Even under less-than-ideal growing conditions, this variety rarely bursts or bolts, ensuring growers can count on a stable and reliable harvest. The uniformity of the tubers makes Ametyst F1 particularly suitable for professional cultivation and sales, but also ideal for home gardeners who expect high quality.

Cultivation and planting advice

Ametyst F1 kohlrabi is suitable for both early cultivation in greenhouses or tunnels and for summer cultivation in the open ground.

• Sowing (pre-sowing): January to July

• Planting out: in a greenhouse or outdoors

• Planting distance: 25 x 25 cm to 30 x 30 cm

Kohlrabi is a heavy feeder, meaning the plants need sufficient nutrients to grow quickly and evenly. Using organic fertilizer or compost at planting, supplemented with nitrogen-rich fertilizer during the growing season, supports the development of compact, crisp tubers.

Harvest period and quality

The Ametyst F1 harvest extends from April to October, depending on sowing and planting time. The tubers remain firm and tender, making them ideal for both fresh consumption and for use in dishes such as stews, stir-fries, or raw in salads.

The early and uniform growth allows growers to plan several successive crops, ensuring continuous availability of high-quality kohlrabi throughout the season.

Culinary applications

The delicate, flattened tubers of Ametyst F1 are versatile in the kitchen:

• Raw in salads or crudités: crunchy and slightly sweet

• Boiled or steamed: retains color and flavor

• Stir-fries: adds a soft texture

• Decorative presentation: uniform, blue tubers are visually attractive

Thanks to its mild and soft taste, Ametyst F1 is suitable for children and for use in a variety of dishes, from classic vegetable dishes to modern, colorful salads.
