Tatsu | F1 Komatsuna Seed

$5.82$561.00AUD gst excl.

Tatsu- A widely-adapted variety of Komatsuna, or Japanese “mustard spinach” is a highly nutritious and productive leafy green commonly found in Japanese cuisine. The name Tatsu means both “dragon,” for its ability to withstand high heat, and “to stand,” as it was selected for upright, dark green plants.

Cooking with Tatsu-Komatsuna can be used similarly to spinach, though it has a softer texture and cooks more quickly. Common for stir-fry, blanched, in soups or salads. Can also be quick-pickled.
