This variety is a robust mustard green with exceptionally feathered, light green leaves and a mild-spicy, aromatic mustard flavor.

Cut-tolerant and open-pollinated – perfect for self-sufficiency and organic cultivation.

  Origin & History

‘Golden Streak’ is a more recent, open-pollinated mustard green selection from England, developed by Tozer Seeds in the 1980s specifically for baby leaf and mixed salad cultivation. It belongs to the species Brassica juncea, which originates from Asia (India, China, Himalaya), where mustard greens have been cultivated for centuries both as a traditional leafy vegetable and as an oil plant. Today, Brassica juncea remains a central part of Asian food culture and is closely related to other Asian greens such as Mizuna, Tatsoi, and Pak Choi.

The variety 'Golden Streak' itself is not a historical landrace but a modern breeding line, created with a focus on decorative, deeply feathered leaves and a mild, aromatic mustard flavor. The breeding goal was to develop a variety distinguished by visual appeal, tender texture, and versatile use in salads and Asian dishes. Today the variety is maintained, propagated, and preserved as a freely accessible, open-pollinated variety by organic seed initiatives. It is considered a valuable addition to the diversity of Asian greens and contributes to safeguarding the genetic breadth of Brassica juncea in organic vegetable cultivation.
