Extraordinary large kohlrabi with light-blue bulbs up to 1.5 kg. Non-woody, mild-tender and juicy taste. Frost-tolerant, storable, suitable for outdoor and greenhouse cultivation. Robust, high-yielding, open-pollinated – ideal for self-sufficiency and organic growing.

  Origin & History

'Dyna' is an open-pollinated, historical autumn variety of kohlrabi (Brassica oleracea var. gongylodes). Traditionally bred as a large-growing, light-blue variety for late autumn cultivation at the "Ekkarthof" in Siegershausen (Canton of Thurgau, Switzerland). It was long popular in Central Europe before modern hybrids displaced it and it nearly fell into oblivion. Its exceptionally large bulbs, weighing over 1 kg, remain tender and juicy without becoming woody.

The variety is well suited and highly valued as an autumn and storage kohlrabi. Kohlrabi has been part of traditional Central European vegetables since the 16th century, originating from wild cabbage in the Mediterranean region. With its mild-tender, juicy flavor and vigorous growth, it is considered an old variety and a true enrichment for heritage gardens. Today it is once again cultivated by organic seed initiatives and preserved as a historical rarity.

 Usage & Cultivation Highlights

The kohlrabi leaves can also be harvested and used.

Thanks to its vigorous growth and frost tolerance, 'Dyna' grows reliably in greenhouses, in open fields, and especially in larger pots. It is easy to care for and impresses with a generous harvest. In addition, it shows good adaptability to different locations and delivers stable yields even under changeable weather conditions. Its decorative, light-blue bulbs ripen evenly and also make the plant a visual enrichment in the garden.
